kn-title=Successful immunotherapy with ipilimumab and nivolumab in a patient with pulmonary sclerosing pneumocytoma
en-subtitle=

en-abstract=
kn-abstract=Pulmonary sclerosing pneumocytoma (PSP) is a rare form of lung cancer that occasionally presents with lymph node and extrapulmonary metastases, and multiple lesions. The treatment of metastatic PSP remains undefined. This study reports the case of a 48-year-old female patient diagnosed with PSP following surgical intervention for a solitary nodule in the left lower lobe. Four years later, recurrence occurred in the left hilar and mediastinal lymph nodes, necessitating an additional resection. Concurrently, sacral metastases developed and required palliative radiotherapy. Genetic analysis identified an AKT1 E17K mutation, characteristic of PSP, and absence of programmed cell death ligand 1 (PD-L1) expression in the tumor. Two years post-recurrence, the tumor recurred in the left mammary gland and mediastinal lymph nodes. Combination immunotherapy with ipilimumab and nivolumab yielded a significantly positive response in this metastatic PSP case. This is the first reported case of successful treatment of multiple distant metastatic PSP with ipilimumab and nivolumab, following the failure of various local treatments. Further case series are warranted to validate the efficacy of immunotherapy in metastatic PSP.

kn-title=Axillary Reactive Lymphoid Hyperplasia, Likely Due to Unicentric Castleman Disease, and the Concurrent Presence of Orbital Mucosa-Associated Lymphoid Tissue (MALT) Lymphoma: A Six-Year Follow-Up Study
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Castleman disease is a lymphadenopathy of unknown cause at a single site, which is designated as unicentric Castleman disease, or at multiple sites designated as multicentric Castleman disease. We present a patient who showed axillary reactive lymphoid hyperplasia, likely due to unicentric Castleman disease, and orbital extranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue (MALT) lymphoma in a six-year follow-up. A 76-year-old man had a painless left axillary mass for an unknown period and also left complete blepharoptosis with no other systemic symptoms. Suspected of lymphoma, iliac bone marrow biopsy showed no anomalous cells, and positron emission tomography demonstrated abnormal uptake at the left axilla and in the left superior anterior orbit. Incisional biopsy of the left axillary mass demonstrated hyperplastic lymphoid follicles with an atrophic germinal center and prominent small vessels in the follicular center, indicative of unicentric Castleman disease. One year later, annual follow-up positron emission tomography disclosed a high uptake site, next to the previously-identified cyst, in the pancreatic body. Trans-gastric fine needle pancreatic biopsy proved adenocarcinoma and he underwent subtotal stomach-preserving pancreaticoduodenectomy with jejunal anastomosis. He was well for six months after the surgery and thus, underwent resection of the left orbital lesion at 78 years old. The pathology of the orbital lesion showed ambiguous nodular structure with massive infiltration with CD20-positive medium-sized lymphoid cells which were κ monotype in immunoglobulin light chain restriction, indicative of MALT lymphoma. In the four-year period of the COVID-19 pandemic, he was healthy and followed with no treatment until the age of 82 years when he underwent radiation (46 Gy) to the left axillary lesion which did not regress. He then underwent eyelid levator muscle plication for left blepharoptosis since the left orbital lesion remained unpalpable. The six-year follow-up showed that concurrent and independent orbital MALT lymphoma and axillary reactive lymphoid hyperplasia, likely due to unicentric Castleman disease, were both stable. The present case illustrates how important it is to make pathological diagnoses in different anatomical lesions after the initial diagnosis of Castleman disease.

kn-title=Presumed Choroidopathy of IgG4-Related Disease Discovered During 16-Year Follow-Up of a Patient With Polycystic Kidney Disease
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Immunoglobulin G4 (IgG4)-related disease is characterized by infiltration with IgG4-producing plasma cells in different organs and the elevation of serum IgG4. We present a patient with polycystic kidney disease in long-term follow-up who developed bilateral lacrimal gland enlargement and presumed IgG4-related choroidopathy at different time points. A 45-year-old woman developed bilateral upper eyelid swelling. Head MRI showed bilateral lacrimal gland enlargement, and the resection on both sides revealed foci of infiltration with lymphocytes and plasma cells in bilateral lacrimal glands. The IgG4-immunostaining did not satisfy the diagnostic criteria. She had been taking oral valsartan 40 mg daily for hypertension with polycystic kidney disease.<br>
<br>
The patient was well until the age of 49 years, when she noticed yellowish vision in the right eye compared to the left eye. The right eye showed multiple yellowish spotty lesions in the deep retina to choroid with a mildly hyperemic optic disc, while the left eye showed the normal fundus. No inflammation was noted in the anterior segments of both eyes. Fundus angiography demonstrated early-phase no-filling with late-phase leakage by fluorescein dye and both early-phase and late-phase no-filling by indocyanine green dye, leading to the diagnosis of acute posterior multifocal placoid pigment epitheliopathy (APMPPE). She began to have oral prednisolone tapered from 30 mg daily and discontinued in a year. At the age of 52 years, she switched to candesartan 8 mg daily and began to have tolvaptan (a selective competitive vasopressin receptor 2 (V2) antagonist) 90 mg daily for polycystic kidney disease with liver cysts. At that time, the lesions in the right eye had mild degeneration.<br>
<br>
The patient was followed once a year ophthalmologically to maintain good vision. At 57 years, serum IgG4, which was measured for the first time on suspicion of IgG4-related disease, was elevated to 269.6 mg/dL. In the following four years to the latest visit at 61 years, she kept stable but high levels of serum IgG4 around 300 mg/dL. Serum IgG4 measurement is helpful to make a clinical diagnosis and, hence, a clinical decision since the spectrum of IgG4-related disease remains obscure.

kn-title=Histological differences related to autophagy in the minor salivary gland between primary and secondary types of Sj?gren's syndrome
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Some forms of Sj?gren’s syndrome (SS) follow a clinical course accompanied by systemic symptoms caused by lymphocyte infiltration and proliferation in the liver, kidneys, and other organs. To better understand the clinical outcomes of SS, here we used minor salivary gland tissues from patients and examine their molecular, biological, and pathological characteristics. A retrospective study was performed, combining clinical data and formalin-fixed paraffin-embedded (FFPE) samples from female patients over 60 years of age who underwent biopsies at Okayama University Hospital. We employed direct digital RNA counting with nCounter? and multiplex immunofluorescence analysis with a PhenoCycler? on the labial gland biopsies. We compared FFPE samples from SS patients who presented with other connective tissue diseases (secondary SS) with those from stable SS patients with symptoms restricted to the exocrine glands (primary SS). Secondary SS tissues showed enhanced epithelial damage and lymphocytic infiltration accompanied by elevated expression of autophagy marker genes in the immune cells of the labial glands. The close intercellular distance between helper T cells and B cells positive for autophagy-associated molecules suggests accelerated autophagy in these lymphocytes and potential B cell activation by helper T cells. These findings indicate that examination of FFPE samples from labial gland biopsies can be an effective tool for evaluating molecular histological differences between secondary and primary SS through multiplexed analysis of gene expression and tissue imaging.

kn-title=Pathological findings in enucleated eyes of patients with neurofibromatosis type 1: report of a case with 15-year follow-up and review of 14 patients in the literature
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Backgrounds Iris nodules are frequently noted as clinical manifestations of neurofibromatosis type 1 but the other intraocular manifestations are rare. The purpose of this study is to present a patient with a phthisic eye who underwent enucleation for a cosmetic reason after 15-year follow-up and also to review 14 patients with enucleation described in the literature.<br>
Case presentation A 17-year-old man with neurofibromatosis type 1 from infancy underwent the enucleation of phthisic left eye and also had the resection of eyelid subcutaneous mass lesions on the left side for a cosmetic reason. He had undergone four-time preceding surgeries for eyelid and orbital mass reduction on the left side in childhood and had developed total retinal detachment 10 years previously. Pathologically, the enucleated eye showed massive retinal gliosis positive for both S-100 and glial fibrillary acidic protein (GFAP) in the area with involvement of the detached retinal neuronal layer, together with a more fibrotic lesion along the choroid which were, in contrast, negative for both S-100 and GFAP. The choroid, ciliary body, and iris did not show apparent neurofibroma while episcleral neurofibroma was present.<br>
Literature review In review of enucleated eyes of 14 patients in the literature, buphthalmic eyes with early-onset glaucoma on the unilateral side was clinically diagnosed in 9 patients who frequently showed varying extent of hemifacial neurofibromatosis which involved the eyelid and orbit on the same side. Pathologically, neurofibromas in varying extent were found in the choroid of 12 patients. One patient showed choroidal malignant melanoma on the left side and fusiform enlargement of the optic nerve on the right side suspected of optic nerve glioma. The phthisic eye in another patient showed massive retinal gliosis similar to the present patient.<br>
Conclusions In summary of the 15 patients with neurofibromatosis type 1, including the present patient, buphthalmic or phthisic eyes with no vision were enucleated for cosmetic reasons and showed choroidal neurofibroma in most patients and massive retinal gliosis in two patients including the present patient.

kn-abstract=Primary myelofibrosis shows widespread fibrosis in the bone marrow and is part of myeloproliferative neoplasms in which gene mutations in hematopoietic stem cells lead to abnormal clonal expansion of one or more lineage of myeloid and erythroid cells and megakaryocytes. Janus kinase (JAK) inhibitors are the main therapeutic regimen for primary myelofibrosis which harbors gene mutations, resulting in continuous activation of JAK-STAT signaling pathway. Since JAK inhibitors modulate immunological state, the administration would have a potential for uveitis. A 67-year-old patient presented with weight loss of 10 kg in the past 2 years after his retirement. He showed normocytic anemia with anisocytosis and abnormal shape, as well as hepatosplenomegaly. Suspected of hematological malignancy, bone marrow biopsy led to the diagnosis of primary myelofibrosis (grade 2) with bizarre megakaryocytes and relative maintenance of myeloid and erythroid lineage. He started to have blood transfusion. Genomic DNA analysis of the peripheral blood showed a pathogenic variant in the exon 9 of calreticulin (CALR) gene while pathogenic variants in Janus kinase-2 (JAK2), and myeloproliferative leukemia virus oncogene (MPL) were absent. He began to have oral ruxolitinib 10 mg daily at the timepoint of 5 months after the initial visit and the dose was increased to 20 mg daily 8 months later but was discontinued further 4 months later because he showed the limited effect of ruxolitinib. He had blood transfusion every week or every 2 weeks in the following 2 months until he noticed blurred vision in the right eye. The right eye showed thick fibrin membrane formation in the anterior chamber in front of the pupil which prevented the fundus from visualization. The left eye showed no inflammation and optic nerve atrophy, sequel to tuberculous meningitis in childhood. The patient started to use 0.1% betamethasone six times daily and 1% atropine once daily as eye drops. A week later, fibrin membrane disappeared and the pupillary area with total iris posterior synechia was visible in the right eye. He regained the vision in the right eye and did not show relapse of uveitis only with topical 0.1% betamethasone. Uveitis might be related with the administration and discontinuation of ruxolitinib.

en-abstract=
kn-abstract=To elucidate long-term outcome in primary conjunctival lymphoma, a review was conducted of 31 consecutive patients: 21 men and 10 women with an age range of 28 to 85 (median, 61) years at presentation and follow-up periods ranging from 1 to 19 (median, 7) years. Conjunctival lymphoma was on the right side in 10 patients, on the left side in 12, and on both sides in 9. Upper, lower, or both fornix lesions in 28 patients were all diagnosed as extranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma), while thick nasal bulbar conjunctival lesions in 3 patients were differently diagnosed as MALT lymphoma, diffuse large B-cell lymphoma, and follicular lymphoma, respectively. Seven patients underwent local radiation (30 Gy): as initial treatment in 5 patients and treatment for relapse in 2 patients. The remaining 24 patients were observed without additional treatment after excisional biopsy: 5 of these 24 patients showed relapse 0.5 to 6 years later and underwent excisional biopsy again that revealed MALT lymphoma. Of the 5 patients with relapse, only one with second-time relapse underwent radiation. Fluorodeoxyglucose positron emission tomography was performed in 18 patients and showed no systemic lesions: high uptake was noted in the residual conjunctival lesions of 4 patients and in the relapsed conjunctival lesions of 3 patients. One patient died of rectal cancer while no patients died of lymphoma. Observation is an option in patients with primary conjunctival lymphoma after excisional biopsy. Radiation is a treatment option in the case of relapse.

kn-title=Endoscopic manifestation of intestinal transplant-associated microangiopathy after stem cell transplantation
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Background Endoscopic features of intestinal transplant-associated microangiopathy (iTAM) have not been comprehensively investigated. This study aimed to examine the endoscopic characteristics of patients diagnosed with iTAM.<br>
Methods This retrospective analysis included 14 patients pathologically diagnosed with iTAM after stem cell transplantation for hematolymphoid neoplasms (n = 13) or thalassemia (n = 1). The sex, age at diagnosis, endoscopic features, and prognosis of each patient were assessed. Serological markers for diagnosing transplant-associated thrombotic microangiopathy were also evaluated.<br>
Results The mean age at the time of iTAM diagnosis was 40.2 years. Patients diagnosed based on the pathognomonic pathological changes of iTAM presented with diverse symptoms at the times of endoscopic examinations, including diarrhea (n = 10), abdominal pain (n = 5), nausea (n = 4), appetite loss (n = 2), bloody stools (n = 2), abdominal discomfort (n = 1), and vomiting (n = 1). At the final follow-up, six patients survived, while eight patients succumbed, with a median time of 100.5 days (range: 52-247) post-diagnosis. Endoscopic manifestations included erythematous mucosa (n = 14), erosions (n = 13), ulcers (n = 9), mucosal edema (n = 9), granular mucosa (n = 9), and villous atrophy (n = 4). Erosions and/or ulcers were primarily observed in the colon (10/14, 71%), followed by the ileum (9/13, 69%), stomach (4/10, 40%), cecum (5/14, 36%), duodenum (3/10, 30%), rectum (4/14, 29%), and esophagus (1/10, 10%). Cytomegalovirus infection (n = 4) and graft-versus-host disease (n = 2) coexisted within the gastrointestinal tract. Patients had de novo prolonged or progressive thrombocytopenia (6/14, 43%), decreased hemoglobin concentration (4/14, 29%), reduced serum haptoglobin level (3/14, 21%), and a sudden and persistent increase in lactate dehydrogenase level (2/14, 14%). Peripheral blood samples from 12 patients were evaluated for schistocytes, with none exceeding 4%.<br>
Conclusions This study provides a comprehensive exploration of the endoscopic characteristics of iTAM. Notably, all patients exhibited erythematous mucosa throughout the gastrointestinal tract, accompanied by prevalent manifestations, such as erosions (93%), ulcers (64%), mucosal edema (64%), granular mucosa (64%), and villous atrophy (29%). Because of the low positivity for serological markers of transplant-associated thrombotic microangiopathy in patients with iTAM, endoscopic evaluation and biopsy of these lesions are crucial, even in the absence of these serological features.

kn-title=Sigle Agent of Posttransplant Cyclophosphamide Without Calcineurin Inhibitor Controls Severity of Experimental Chronic GVHD
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Chronic graft-versus-host disease (GVHD) is a major cause of late death and morbidity following allogeneic hematopoietic cell transplantation (HCT), but its pathogenesis remains unclear. Recently, haplo-identical HCT with post-transplant cyclophosphamide (Haplo-HCT with PTCY) was found to achieve a low incidence rate of acute GVHD and chronic GVHD. However, while the pathogenesis of acute GVHD following Haplo-HCT with PTCY has been well investigated, that of chronic GVHD remains to be elucidated, especially in HLA-matched HCT with PTCY. Based on its safety profile, PTCY is currently applied for the human leucocyte antigen (HLA)-matched HCT setting. Here, we investigated the mechanisms of chronic GVHD following HLA-matched HCT with PTCY using a well-defined mouse chronic GVHD model. PTCY attenuated clinical and pathological chronic GVHD by suppressing effector T-cells and preserving regulatory T-cells compared with a control group. Additionally, we demonstrated that cyclosporine A (CsA) did not show any additional positive effects on attenuation of GVHD in PTCY-treated recipients. These results suggest that monotherapy with PTCY without CsA could be a promising strategy for the prevention of chronic GVHD following HLA-matched HCT.

en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=The objective of this study was to clarify the long-term prognosis of patients with gastric mucosa-associated lymphoid tissue (MALT) lymphoma with additional copies of MALT1. In this multicenter retrospective study, we enrolled 145 patients with gastric MALT lymphoma who underwent fluorescence in situ hybridization (FISH) analysis to detect t(11;18) translocation. The patient cohort was divided into three groups: Group A (n?=?87), comprising individuals devoid of the t(11;18) translocation or extra MALT1 copies; Group B (n?=?27), encompassing patients characterized by the presence of the t(11;18) translocation; and Group C (n?=?31), including patients with extra MALT1 copies. The clinical outcomes in each cohort were collected. Over the course of a mean follow-up of 8.5?±?4.2 years, one patient died of progressive MALT lymphoma, while 15 patients died due to etiologies unrelated to lymphoma. The progression or relapse of MALT lymphoma was observed in 11 patients: three in Group A, two in Group B, and six in Group C. In Groups A, B, and C, the 10-year overall survival rates were 82.5%, 93.8%, and 86.4%, respectively, and the 10-year event-free survival rates were 96.1%, 96.0%, and 82.9%, respectively. The event-free survival rate in Group C was significantly lower than that in Group A. However, no differences were observed in the 10-year event-free survival rates among individuals limited to stage I or II1 disease (equivalent to excluding patients with stage IV disease in this study, as there were no patients with stage II2), with rates of 98.6%, 95.8%, and 92.3% for Groups A, B, and C, respectively. In conclusion, the presence of extra copies of MALT1 was identified as an inferior prognostic determinant of event-free survival. Consequently, trisomy/tetrasomy 18 may serve as an indicator of progression and refractoriness to therapeutic intervention in patients with gastric MALT lymphoma, particularly stage IV gastric MALT lymphoma.

kn-title=Regression of Necrotic Lesions after Methotrexate Withdrawal in Patients with Methotrexate-Associated Lymphoproliferative Disorders: A Retrospective CT Study
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=This retrospective study investigated whether necrotic lesions detected on a computed tomography (CT) scan are more regressive than non-necrotic lesions after methotrexate withdrawal in patients pathologically diagnosed with methotrexate-associated lymphoproliferative disorders (MTX-LPD). In total, 89 lesions extracted from 24 patients on CT scans were included in the analysis. All patients had been evaluated for the presence of necrosis within lesions via CT scan upon first suspicion of MTX-LPD (baseline CT scan). The percentage lesion size reduction between the baseline and initial follow-up CT scan was calculated. The association between necrosis within lesions and size changes was estimated via linear regression analyses using both crude and adjusted models. Necrosis was significantly more common in extranodal lesions (27 out of 30 lesions, 90%) than in nodal lesions (9 out of 59 lesions, 15%, p<0.001). In the crude model, the regression of necrotic lesions was 58.5% greater than that of non-necrotic lesions; the difference was statistically significant (p<0.001). Additionally, the longest diameter of necrotic lesions at the baseline CT scan was significantly greater than that of non-necrotic lesions (p<0.001). Based on the adjusted model, necrotic lesions showed 49.3% greater regression than non-necrotic lesions (p=0.017). Necrosis detected on a CT scan was found to be an independent predictor of regression after MTX withdrawal in patients with MTX-LPD.

kn-title=Resection depth for small colorectal polyps comparing cold snare polypectomy, hot snare polypectomy and underwater endoscopic mucosal resection
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Background and study aims?Small colorectal polyps are removed by various methods, including cold snare polypectomy (CSP), hot snare polypectomy (HSP), and underwater endoscopic mucosal resection (UEMR), but the indications for using these methods are unclear. We retrospectively assessed the efficacy of CSP, HSP, and UEMR for small polyps, focusing on the depth of the resected specimens.<br>
Patients and methods?Outpatients with non-pedunculated small polyps (endoscopically diagnosed as 6 to 9?mm), resected by two endoscopists between July 2019 and September 2020, were enrolled. We histologically evaluated the specimens resected via CSP, HSP, and UEMR. The main outcome was the containment rate of the muscularis mucosa (MM) and submucosa (SM) tissues.<br>
Results?Forty polyps resected via CSP (n?=?14), HSP (n?=?12), or UEMR (n?=?14) were enrolled after excluding 13 polyps with resection depths that were difficult to determine. The rates of specimens containing MM and SM tissue differed significantly (57?% and 29?% for CSP, 92?% and 83?% for HSP, and 100?% and 100?% for UEMR, respectively (P?=?0.005 for MM and P?<?0.001 for SM tissue). Multiple logistic regression analysis showed UEMR was an independent factor relating to the containment of SM tissue. The thickness of SM tissue by CSP, HSP, and UEMR were 52 μm, 623 μm, and 1119 μm, respectively (P?<?0.001). The thickness by CSP was significantly less than those by HSP and UEMR (P?<?0.001, Bonferroni correction).<br>
Conclusions?UEMR could be the best method to contain SM tissue without injection. Further studies are needed to evaluate the indication of UEMR for small polyps.

kn-title=Connective tissue mast cells store and release noradrenaline
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Mast cells are present in mucosal and connective tissues throughout the body. They synthesize and release a wide variety of bioactive molecules, such as histamine, proteases, and cytokines. In this study, we found that a population of connective tissue mast cells (CTMCs) stores and releases noradrenaline, originating from sympathetic nerves. Noradrenaline-storing cells, not neuronal fibers, were predominantly identified in the connective tissues of the skin, mammary gland, gastrointestinal tract, bronchus, thymus, and pancreas in wild-type mice but were absent in mast cell-deficient W-sash c-kit mutant KitW-sh/W-sh mice. In vitro studies using bone marrow-derived mast cells revealed that extracellular noradrenaline was taken up but not synthesized. Upon ionomycin stimulation, noradrenaline was released. Electron microscopy analyses further suggested that noradrenaline is stored in and released from the secretory granules of mast cells. Finally, we found that noradrenaline-storing CTMCs express organic cation transporter 3 (Oct3), which is also known as an extraneuronal monoamine transporter, SLC22A3. Our findings indicate that mast cells may play a role in regulating noradrenaline concentration by storing and releasing it in somatic tissues.

en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=To determine the endoscopic and clinical features of localized gastric amyloid light-chain (AL) amyloidosis, we retrospectively examined the characteristics of nine patients (eight men and one woman) encountered by the hospitals in our network. Lesions were predominantly flat and depressed with surface vascular dilatation (n=5); others were characterized by subepithelial lesions (n=2), mucosal color change (n=1), and a mass-like morphology with swollen mucosal folds (n=1). Colonoscopy (n=7), video capsule enteroscopy (n=2), serum (n=5) and urine immunoelectrophoresis (n=4), and bone marrow examination (n=3) were performed to exclude involvement of organs other than the stomach. As treatment for gastric lesions of AL amyloidosis, one patient each underwent endoscopic submucosal dissection (n=1) and argon plasma coagulation (n=1), while the remaining seven patients underwent no specific treatment. During a mean follow-up of 4.2 years, one patient died 3.2 years after diagnosis, but the cause of death, which occurred in another hospital, was unknown. The remaining eight patients were alive at the last visit. In conclusion, although localized gastric AL amyloidosis can show various macroscopic features on esophagogastroduodenoscopy, flat, depressed lesions with vascular dilatation on the surface are predominant.

kn-title=Resection of Orbital Myxoma With Magnetic Resonance Imaging Evidence of Ethmoid Sinus Origin: Case Report and Review of 20 Patients in the Literature
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=A 41-year-old woman showed a palpable mass at the superonasal orbital edge on the right side. Magnetic resonance imaging demonstrated a lobulated fluid-containing tubular mass which extended anteriorly to posteriorly along the medial orbital wall, nasal to the eyeball. She was followed once a year for 8 years until the age of 49 years when she decided to undergo surgical resection because of the enlarged mass. The lobulated large mass was resected and the pathology showed sparsely distributed spindle cells, positive for CD34, in alcian blue-positive mucous substances, indicative of myxoma. Postoperative magnetic resonance imaging showed residual lobulated tubular mass along the optic nerve on the medial side and superior to the eyeball. The residual orbital mass showed stable structure with more evident connection with the ethmoid sinus lesion, suggestive of the ethmoid origin, in 12 years until the age of 61 years. In the review of 20 patients with orbital myxomas in the literature, in addition to this case, roughly classified locations in the orbit were retrobulbar in 8 patients, on the lateral side of the orbit in 4, on the superior side in 6, on the medial side in 1 (this patient), and in the orbit with no specific description in 2. In pathological examinations, immunohistochemistry was not done in 8 patients, done but all negative in 2, and positive in 11 patients: nerve sheath myxoma was diagnosed in 3 patients based on positive S100 staining. Orbital myxoma is rare but considered in differential diagnosis of orbital masses.

en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Objectives: Transient fever and electrocoagulation syndrome after colorectal endoscopic submucosal dissection (ESD) remain a challenge. The aim of this study was to assess the risk factors of post-ESD fever and post-ESD coagulation syndrome (PECS), focusing on the involvement of immunosuppressive drugs and steroids (IM).<br>
Methods: This retrospective analysis included 510 patients who underwent colorectal ESD at Okayama University Hospital from 2015 to 2020. The incidence rate, clinical outcome, and factors associated with post-ESD fever and PECS were investigated.<br>
Results: Post-ESD fever and PECS occurred in 63 patients (12.4%) and 43 patients (8.4%), respectively. In multivariate analysis, the American Society of Anesthesiologists Physical Status ?3, the use of immunosuppressants or prednisolone ?5mg (IM group), and injury to muscle layer/perforation were significantly associated with post-ESD fever. In PECS, IM group, tumors located on the right side, treatment time ?60 min, injury to the muscle layer, and multiple lesions were independent risk factors. Both post-ESD fever and PECS improved conservatively in the IM group, and no serious complication was observed.<br>
Conclusions: The use of IM was a risk factor for both post-ESD fever and PECS. However, there were no serious complications in colorectal ESD for patients taking IM.

kn-abstract=Background and study aims　Because the endoscopic treatment for non-ampullary duodenal adenoma (NADA) has a non-negligible risk of adverse events (AEs), a safe and easy treatment for NADA is desirable. This was a multicenter prospective trial evaluating the efficacy and safety of cold forceps polypectomy (CFP) for diminutive NADAs.<br>
Patients and methods　This study was prospectively conducted at six general hospitals and one university hospital. The inclusion criteria were histologic and endoscopic diagnosis of low-grade NADA measuring???6?mm. A second endoscopy was scheduled for 1 month after CFP. After confirmation of the success of CFP, 6-month and 12-month surveillance endoscopies were scheduled. The primary endpoint was the endoscopic and histologic disease disappearance rates at the 12-month endoscopy.<br>
Results　Thirty-nine lesions from 38 patients were prospectively included. Median tumor size at enrollment was 5?mm (range 3?6?mm). There were four cases of remnant lesions at the second endoscopy, and the lesion disappearance rate of single CFP was 89.7?% (35?/39; 95?% confidence interval (CI), 76.9?%?97.9?%). In three cases, complete removal of the lesion was achieved with a single re-CFP, but one case required four repeat CFPs. The lesion disappearance rate at 12-month endoscopy was 97.4?% (38?/39; 95?%CI, 86.8?%?99.5?%). During the follow-up period, no AEs related to CFP were observed.<br>
Conclusions　CFP for NADA???6?mm was safe and effective in this study. This common endoscopic method to remove lesions may be an option for treatment of diminutive NADAs.

en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=An ectopic pancreas is defined as pancreatic tissue outside its normal location, anatomically separated from the pancreas.<br>
　The transcription factor pancreas/duodenum homeobox protein 1 (PDX1) is involved in maintaining the pancreas and functions in early pancreatic development, beta cell differentiation, and endocrine non beta cells. Pancreatic transcription factor 1 subunit alpha (PTF1A) affects exocrine cell formation and regulation of acinar cell identity, and is expressed in exocrine cells as a transcription factor. The depletion of SALL4 disrupts self-renewal and induces differentiation.<br>
　To clarify which of PDX1, PTF1A, or SALL4 determines the difference in Heinrich's classification, we examined the localization and number of positive cells. We analyzed the differential expression of PDX1, PTF1A, and SALL4 in large and small ducts in ectopic pancreas by immunohistochemistry. Results showed that the number of PTF1A-positive cells in large ducts was more widespread in type I than in type II in the gastro-duodenum, and more SALL4-positive cells were noticed in large ducts than in small ducts in the gastro-duodenum of type II. Our results revealed that PTF1A might promote exocrine differentiation in developing the pancreatic tissues, and that those with widespread expression differentiate into exocrine cells.

kn-abstract=The feasibility of lymphocyte isolation and flow cytometry using a single endoscopic biopsy specimen from the gastrointestinal tract of patients who have undergone hematopoietic stem cell transplantation has not been investigated. We acquired 51 endoscopic biopsy specimens from the gastrointestinal tract of 35 patients. We divided the flow cytometry samples into two groups: group A, successful lymphocyte isolation (n=24), and group B, incomplete isolation (n=27). We compared the backgrounds of the samples between the groups to reveal crucial elements in the successful isolation of lymphocytes residing in the gastrointestinal tract. Comparison between the groups revealed lymphocyte isolation success rates differed between biopsy sites. Isolation was most successful in samples from the duodenum (8/9, 88.9%), followed by the ileum (4/8, 50.0%), large intestine (4/11, 36.4%), and stomach (8/23, 34.8%). Tacrolimus was used more frequently in group B (92.6%) than in group A (62.5%) (p=0.015). Logistic regression analysis revealed that isolation from the duodenum or ileum was a significant factor for successful isolation, while tacrolimus use was not statistically significant. In conclusion, the duodenum and ileum are more suitable sites than the stomach and colorectum for acquiring samples for flow cytometry.

en-abstract=
kn-abstract=Recent studies have advanced our understanding of the pathophysiology of autoimmune gastritis, particularly its molecular aspects. The most noteworthy recent advancement lies in the identification of several candidate genes implicated in the pathogenesis of pernicious anemia through genome-wide association studies. These genes include PTPN22, PNPT1, HLA-DQB1, and IL2RA. Recent studies have also directed attention towards other genes such as ATP4A, ATP4B, AIRE, SLC26A7, SLC26A9, and BACH2 polymorphism. In-depth investigations have been conducted on lymphocytes and cytokines, including T helper 17 cells, interleukin (IL)-17A, IL-17E, IL-17F, IL-21, IL-19, tumor necrosis factor-α, IL-15, transforming growth factor-β1, IL-13, and diminished levels of IL-27. Animal studies have explored the involvement of roseolovirus and H. pylori in relation to the onset of the disease and the process of carcinogenesis, respectively. Recent studies have comprehensively examined the involvement of autoantibodies, serum pepsinogen, and esophagogastroduodenoscopy in the diagnosis of autoimmune gastritis. The current focus lies on individuals demonstrating atypical presentations of the disease, including those diagnosed in childhood, those yielding negative results for autoantibodies, and those lacking the typical endoscopic characteristics of mucosal atrophy. Here, we discuss the recent developments in this field, focusing on genetic predisposition, epigenetic modifications, lymphocytes, cytokines, oxidative stress, infectious agents, proteins, microRNAs, autoantibodies, serum pepsinogen, gastrin, esophagogastroduodenoscopy and microscopic findings, and the risk of gastric neoplasm.

kn-title=Collagenous Colitis in a Patient With Gastric Cancer Who Underwent Chemotherapy
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Herein, we present a case of collagenous colitis in a patient who underwent chemotherapy for gastric cancer, comprising five cycles of S-1 plus oxaliplatin and trastuzumab, followed by five cycles of paclitaxel and ramucirumab and seven cycles of nivolumab. The subsequent initiation of trastuzumab deruxtecan chemotherapy led to the development of grade 3 diarrhea after the second cycle of treatment. Collagenous colitis was diagnosed via colonoscopy and biopsy. The patient's diarrhea improved following the cessation of lansoprazole. This case highlights the importance of considering collagenous colitis as a differential diagnosis, in addition to chemotherapy-induced colitis and immune-related adverse event (irAE) colitis, in patients with similar clinical presentations.

kn-title=Bilateral Lacrimal Gland Mantle Cell Lymphoma in 11-Year Follow-Up: Case Report and Review of 48 Cases With Ocular Adnexal Presentation in the Literature
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=A 63-year-old woman, with 11-year history of breast cancer, showed bilateral lacrimal gland enlargement on magnetic resonance imaging. Gallium-67 scintigraphy, as the standard at that time in 2004, demonstrated abnormally high uptake only in bilateral lacrimal glands. The lacrimal glands were extirpated and the pathological diagnosis was mantle cell lymphoma (MCL). She underwent bilateral orbital radiation, based on no uptake of gallium-67 in other sites of the body. In a month, bone marrow biopsy revealed the infiltration with MCL, positive for cyclin D1. She showed hepatic lymphadenopathy and splenomegaly, and so received 2 cycles of alternating Hyper-CVAD therapy and high-dose methotrexate with cytarabine, combined with rituximab, in 2 months, leading to complete remission. She underwent autologous peripheral blood stem cell transplantation and was well until the age of 68 years when she showed a recurrent intratracheal submucosal lesion of lymphoma and underwent one course of reduced-dose CHOP combined with rituximab. Next year, the left rib resection revealed the metastasis of breast adenocarcinoma, leading to daily oral letrozole. Further 2 years later, computed tomographic scan demonstrated multiple submucosal nodular lesions in the trachea and bronchi, together with cervical and supraclavicular lymphadenopathy, and intratracheal lesion biopsy and bone marrow biopsy proved the involvement with MCL. She underwent 2 courses of bendamustine and rituximab, resulting in complete remission but died of metastatic breast cancer at the age of 74 years. Clinical features in 48 previous cases with ocular adnexal MCL in the literature were summarized in this study.

kn-title=Review of lymphoma in the duodenum: An update of diagnosis and management
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=The presentation, subtype, and macroscopic images of lymphoma vary depending on the site of the tumor within the gastrointestinal tract. We searched PubMed for publications between January 1, 2012 and October 10, 2022, and retrieved 130 articles relating to duodenal lymphoma. A further 22 articles were added based on the manual screening of relevant articles, yielding 152 articles for full-text review. The most predominant primary duodenal lymphoma was follicular lymphoma. In this review, we provide an update of the diagnosis and man-agement of representative lymphoma subtypes occurring in the duodenum: Follicular lymphoma, diffuse large B-cell lymphoma, extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue, mantle cell lymphoma, and T-cell lymphomas.

kn-title=A Novel Method for Detecting Lanthanum Phosphate Deposition in the Gastroduodenal Mucosa Using Fluorescence Microscopy
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Diagnostic utility of fluorescence microscopy for lanthanum phosphate deposition in the gastrointestinal mucosa has not been reported previously. In this study, we comparatively assessed the light, electron, and fluorescence microscopy features of gastroduodenal lanthanum phosphate deposition in 10 patients with deposits in the stomach and 5 patients with deposits in the duodenum. During light microscopy, lanthanum deposits were observed as dark-brown, needle-shaped, or crystalloid structures and pale red amorphous materials. During electron microscopy, the deposited material appeared as bright aggregates. Fluorescence microscopy also revealed lanthanum deposits as bright areas under green, red, and blue filters. The deposits were more easily recognizable on electron and fluorescence microscopy than on light microscopy. Furthermore, during fluorescence microscopy, the green filter provided the most clear visualization of lanthanum phosphate. In conclusion, fluorescence microscopy with a green filter is useful in determining the degree and extent of lanthanum deposition in the gastroduodenal mucosa.

kn-title=Impact of cancer-associated fibroblasts on survival of patients with ampullary carcinoma
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Background: Cancer-associated fibroblasts (CAFs) reportedly enhance the progression of gastrointestinal surgery; however, the role of CAFs in ampullary carcinomas remains poorly examined. This study aimed to investigate the effect of CAFs on the survival of patients with ampullary carcinoma. <br>
Materials and methods: A retrospective analysis of 67 patients who underwent pancreatoduodenectomy between January 2000 and December 2021 was performed. CAFs were defined as spindle-shaped cells that expressed alpha-smooth muscle actin (alpha-SMA) and fibroblast activation protein (FAP). The impact of CAFs on survival, including recurrence-free (RFS) and disease-specific survival (DSS), as well as prognostic factors associated with survival, was analyzed. <br>
Results: The high-alpha-SMA group had significantly worse 5-year RFS (47.6% vs. 82.2%, p = 0.003) and 5-year DSS (67.5% vs. 93.3%, p = 0.01) than the low-alpha-SMA group. RFS (p = 0.04) and DSS (p = 0.02) in the high-FAP group were significantly worse than those in the low-FAP group. Multivariable analyses found that high alpha-SMA expression was an independent predictor of RFS [hazard ratio (HR): 3.68; 95% confidence intervals (CI): 1.21-12.4; p = 0.02] and DSS (HR: 8.54; 95% CI: 1.21-170; p = 0.03). <br>
Conclusions: CAFs, particularly alpha-SMA, can be useful predictors of survival in patients undergoing radical resection for ampullary carcinomas.

kn-title=Increased CCR4+ and Decreased Central Memory CD4+ T Lymphocytes in the Background Gastric Mucosa of Patients Developing Gastric Cancer After Helicobacter pylori Eradication: An Exploratory Study
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=The composition of lymphocytes in the gastric mucosa following the eradication of Helicobacter pylori (H. pylori) in patients with and without gastric cancer has not been compared. This study performed a single spot analysis of gastric mucosal lymphocytes after H. pylori eradication in patients with (n = 13) and without (n = 20) gastric cancer. Our comprehensive analysis of lymphocyte composition in the gastric mucosa revealed that: i) the proportion of CD8+/CD3+ cells was relatively higher in the peri-tumor mucosa than in the background mucosa; ii) the proportion of CCR4+/CD3+ cells was higher, and the ratio of CD62L+/CD3+CD4+ cells was relatively lower in the gastric mucosa of cancer patients than in non-cancer patients; and iii) the proportion of CD45RA-CD62L+/CD3+CD4+ cells, namely, the central memory CD4+ T -cell fraction, was lower in the gastric mucosa of cancer patients than in non-cancer patients. Although the exact mechanism of the altered proportions of CCR4+/CD3+ and central memory CD4+ cells in the gastric mucosa of patients with cancer is unknown, focusing on lymphocytes in the gastric mucosa might help improve our understanding of gastric cancer development after H. pylori eradication.

kn-title=Scattered Tiny Whitish Protrusions in the Stomach Are a Clue to the Diagnosis of Autoimmune Gastritis
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Herein, we report two patients with autoimmune gastritis who had undergone multiple esophagogastroduodenoscopy procedures for 17 and 9 years, respectively, before their diagnosis. Instead, they had been diagnosed with and treated for Helicobacter pylori-associated gastritis. The correct diagnosis was made when scatterings of tiny whitish protrusions in the gastric mucosa were detected on esophagogastroduodenoscopy. Our findings suggest that scattered tiny whitish bumps may be a clue to the diagnosis of autoimmune gastritis.

en-subtitle=

en-abstract=
kn-abstract=It is difficult to histologically differentiate extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma) from chronic gastritis (CG)/ reactive lymphoid hyperplasia (RLH). To determine whether immunohistochemistry for IRTA1 and MNDA can differentiate gastric MALT lymphoma from CG/RLH, we investigated 81 stomach biopsy specimens [Wotherspoon grade (WG) 1, 11 cases; WG 2, 9 cases; WG 3, 20 cases; WG 4, 31 cases; and WG 5, 10 cases]. According to a previously reported algorithm involving PCR for immunoglobulin heavy (IgH) chain locus rearrangement, all 81 cases were divided into three groups: CG/RLH (55 cases), MALT lymphoma (19 cases) groups, and IgH undetectable group (7 cases). We analyzed the CG/RLH and MALT lymphoma groups. The median percentage of IRTA1-positive cells was 0% (range 0%-90.6%) in the CG/RLH group and 43.5% (range 0%-97.6%) in the MALT lymphoma group (p < 0.0001). The median percentage of MNDA-positive cells was 32.4% (range 0%-97.6%) in the CG/RLH group and 55.1% (range 0%-97.6%) in the MALT lymphoma group (p = 0.0044). These results indicate that immunohistochemistry for IRTA1 and MNDA can help dif-ferentiate gastric MALT lymphoma from CG/RLH.

kn-title=Multiple White Plaques in the Esophagus: A Possible Case of Esophageal Mucosal Alteration Associated With Immune-Related Adverse Events of Immune Checkpoint Inhibitors
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=We report two cases of multiple white plaques in the esophagus that emerged after the administration of immune checkpoint inhibitors. Both patients developed enterocolitis as immune-related adverse events associated with immune checkpoint inhibitors. Esophagogastroduodenoscopy revealed duodenal involvement and multiple white plaques in the esophagus. A biopsy of the esophagus showed predominant CD3+ lymphocyte infiltration, suggesting that esophageal mucosal alterations were associated with immune-related adverse events. In addition, histopathology showed keratinized stratified squamous epithelium in the first case while increased inflammatory cell infiltration in the intraepithelial and subepithelial layers was observed in the second case. These data suggest a different pathogenesis of the multiple esophageal white plaques between the two cases. Although further investigation is needed to elucidate the significance of these observations, recognition of the esophageal plaques may be important for prompt diagnosis of immune-related adverse events when associated with immune checkpoint inhibitors.

kn-title=Zinc Acetate Dihydrate Tablet-Associated Gastritis Occurring in a Post-Hematopoietic Stem Cell Transplant Recipient
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=A 65-year-old Japanese woman underwent umbilical cord blood transplantation for acute myeloid leukemia. Zinc acetate dihydrate tablets were administered for hypozincemia after transplantation, and vomiting and appetite loss occurred soon thereafter. Esophagogastroduodenoscopy revealed mucosal redness, erosion, white coat adhesion, and ulcers. Although graft-versus-host disease, intestinal transplant-associated microangiopathy, and cytomegalovirus infection were considered as possible causes, we diagnosed the patient with zinc acetate dihydrate tablet-associated gastric mucosal alterations based on the endoscopic features. This case reinforces the notion that medication-associated gastric lesions should be suspected in patients taking zinc acetate dihydrate tablets.

kn-title=Prevention of non-infectious pulmonary complications after intra-bone marrow stem cell transplantation in mice
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Non-infectious pulmonary complications including idiopathic pneumonia syndrome (IPS) and bronchiolitis obliterans syndrome (BOS), which are clinical and diagnostic manifestations of lung chronic graft-versus-host disease (GVHD), cause significant mortality after allogeneic stem cell transplantation (SCT). Increasing evidence suggests that alloantigen reactions in lung tissue play a central role in the pathogenesis of IPS and BOS; however, the mechanism is not fully understood. Several clinical and experimental studies have reported that intrabone marrow (IBM)-SCT provides high rates of engraftment and is associated with a low incidence of acute GVHD. In the present study, allogeneic SCT was conducted in mouse models of IPS and BOS, to compare intravenous (IV)-SCT with IBM-SCT. Allogeneic IBM-SCT improved the clinical and pathological outcomes of pulmonary complications compared to those of IV-SCT. The mechanisms underlying the reductions in pulmonary complications in IBM-SCT mice were explored. The infiltrating lung cells were mainly CD11b+ myeloid and CD3+ T cells, in the same proportions as in transplanted donor cells. In an in vivo bioluminescence imaging, a higher proportion of injected donor cells was detected in the lung during the early phase (1 h after IV-SCT) than after IBM-SCT (16.7 +/- 1.1 vs. 3.1 +/- 0.7 x 10(5) photons/s/animal, IV-SCT vs. IBM-SCT, P = 1.90 x 10(-10)). In the late phase (5 days) after SCT, there were also significantly more donor cells in the lung after IV-SCT than after IBM-SCT or allogeneic-SCT (508.5 +/- 66.1 vs. 160.1 +/- 61.9 x 10(6) photons/s/animal, IV-SCT vs. IBM-SCT, P = 0.001), suggesting that the allogeneic reaction induces sustained donor cell infiltration in the lung during the late phase. These results demonstrated that IBM-SCT is capable of reducing injected donor cells in the lung; IBM-SCT decreases donor cell infiltration. IBM-SCT therefore represents a promising transplantation strategy for reducing pulmonary complications, by suppressing the first step in the pathophysiology of chronic GVHD.

kn-title=Endoscopic findings of gastric neoplasms in familial adenomatous polyposis are associated with the phenotypic variations and grades of dysplasia
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Patients with familial adenomatous polyposis (FAP) are at increased risk of developing gastric neoplasms. However, endoscopic findings have not been sufficiently investigated. We investigated the phenotypic expression of gastric adenoma (low-grade dysplasia) and gastric cancer (high-grade dysplasia or carcinoma) in patients with FAP and clarified their relationships to endoscopic findings. Of 29 patients with FAP who underwent esophagogastroduodenoscopy between 2005 and 2020, 11 (38%) had histologically confirmed gastric neoplasms, including 23 lesions of gastric adenoma and 9 lesions of gastric cancer. The gastric neoplasms were classified into 3 phenotypes (gastric, mixed, or intestinal type) according to the immunostaining results and evaluated for location (U or M region: upper or middle third of the stomach or L region: lower third of the stomach), color (same as the background mucosa, whitish, or reddish), macroscopic type (elevated, flat, or depressed), background mucosal atrophy (present or absent), fundic gland polyps in the surrounding mucosa (present or absent), and morphologic changes in tumor size. Elevated whitish gastric adenomas were further subdivided by macroscopic type (flat elevated, protruded, or elevated with a central depression) and color (milky- or pinkish-white). The gastric adenomas included gastric (11/23, 48%), mixed (4/23, 17%), and intestinal (8/23, 35%) phenotypes. In contrast, no lesions of gastric cancers showed a gastric phenotype (0/9, 0%), while 5 (56%) and 4 (44%) lesions were intestinal and mixed phenotypes, respectively. Gastric cancers were significantly more likely than gastric adenomas to present as reddish depressed lesions with gastric atrophy. All gastric-type adenomas occurred in non-atrophic mucosa, in mucosa with fundic gland polyps in the periphery, in the U or M region, and as flat elevated or protruded lesions with a milky-white color. Half of the lesions increased in size. Meanwhile, the typical endoscopic features of intestinal-type adenomas included occurrence in the L region and elevated pinkish-white lesions with central depression. None of the intestinal-type adenomas increased in size during the observation period. We believe that these endoscopic features will be useful for the prompt diagnosis and appropriate management of gastric neoplasms in patients with FAP.

kn-title=Diffuse large B-cell lymphoma in the course of systemic sarcoidosis: A case report and review of 30 Japanese patients with sarcoidosis-lymphoma syndrome
en-subtitle=

kn-abstract=We report a patient with sarcoidosis who developed diffuse large B-cell lymphoma. A 71-year-old woman with persistent cough was diagnosed pathologically with sarcoidosis by resection of the right upper lung lobe with a nodule after an unsuccess?ful attempt of transbronchial needle aspiration for mediastinal lymphadenopathy. She was referred for an eye examination and found to have spotty retinal degeneration on the lower fundi of both eyes, together with residual macular edema and vitreous opacity in the left eye. At 76 years, she underwent cataract surgery and vitrectomy to gain a visual acuity of 0.6 in the left eye. At 77 years, she developed a cough and fever, and showed leukopenia and thrombocytopenia. Computed tomography showed multiple small nodular lesions in both lungs, and bilateral hilar, mediastinal, and hepatic lymphadenopathy. Fluorodeoxyglucose positron emission tomography demonstrated high uptake in the liver, spleen, pancreatic head, and lymph nodes. Bone marrow biopsy was intact, but liver biopsy revealed anomalous large lymphoid cells in the sinusoids which were positive for CD20 and showed a high Ki-67 index, leading to the diagnosis of diffuse large B-cell lymphoma. Chemotherapy with 8 courses of THP-COP (cyclophosphamide, pirarubicin, vincristine, and prednisolone) with rituximab, followed by intra?thecal injection of methotrexate, cytarabine, and dexamethasone, resulted in complete remission. She maintained complete remission for 10 years until 88 years old at present. The literature review found 30 patients, including this case, who developed lymphoma in the course of sarcoidosis. A novel pathological diagnosis is required in the setting of acute ymptomatic changes and novel lesions on imaging in patients with sarcoidosis.

kn-title=Site-specific differences in T lymphocyte composition of the gastric mucosa after Helicobacter pylori eradication
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=In our earlier work, we revealed that inflammation of the lesser curvature of the gastric body and antrum could constitute independent risk factors for gastric cancer development, while inflammation of the greater curvature was not. The aims of this study were as follows: first, to reveal the differences between T lymphocyte populations of the gastric antrum and the greater and lesser curvatures of the gastric body in patients after Helicobacter pylori eradication; second, to analyze the correlation between the composition of the stomach-resident T lymphocytes and time from H. pylori eradication; and third, to evaluate the sex differences in T lymphocyte subsets after H. pylori eradication. To investigate site-specific differences in stomach-resident T lymphocytes after H. pylori eradication, we performed flow cytometry analysis on samples taken from the gastric antrum, greater curvature of the gastric body, and lesser curvature of the gastric body of 20 patients. We also analyzed the correlation between the composition of the stomach-resident T lymphocytes and the time from H. pylori eradication. The lymphocyte subsets of the antrum and lesser curvature of the body were similar. In contrast, compared to those in the greater curvature of the gastric body, CD4(+)/CD3(+) lymphocyte subsets (43.8 +/- 19.4% vs 31.7 +/- 14.6%) were elevated in the lesser curvature of the body, whereas CD8(+)/CD3(+) (67.1 +/- 21.3% vs 80.4 +/- 12.0%), CD7(+)/CD3(+) (91.2 +/- 4.6% vs 93.7 +/- 3.8%), CCR4(+)/CD3(+) (7.7 +/- 8.1% vs 10.4 +/- 7.0%), CD45RA(+)/CD3(+)CD4(+) (27.2 +/- 24.8% vs 39.5 +/- 20.8%), and CD45RA(+)/CD3(+)CD4(-) (14.2 +/- 11.1% vs 18.7 +/- 11.5) were lower. Linear regression analysis showed a negative correlation between the time after H. pylori eradication and CD4(+)/CD3(+) (P < .05, R-2 = 0.198). There were no significant differences between men and women with respect to the lymphocyte populations. These results indicate that there are site-specific differences in lymphocyte composition in the stomach after H. pylori eradication.

kn-abstract=A 45-year-old Japanese man underwent esophagogastroduodenoscopy, which revealed spotty redness at the gastric fornix, mucosal swelling, diffuse redness in the corpus, and mucosal atrophy in the gastric angle and antrum. Histological examination showed rod-shaped bacteria that appeared larger than Helicobacter pylori. The patient tested positive for rapid urease test, and serum anti-H. pylori IgG antibody test results were negative. Further examination of the bacteria revealed that H. suis antibody test was positive, and the presence of H. suis was confirmed using H. suis-specific real-time PCR. H. suis was successfully eradicated after triple therapy with vonoprazan, amoxicillin, and clarithromycin. This case reinforces the notion that non-H. pylori Helicobacter species such as H. suis and H. heilmannii may be involved in the pathogenesis of active gastritis in patients who test negative for H. pylori antibodies.

en-abstract=
kn-abstract=Objective This study aimed to determine the prevalence and endoscopic features of zinc acetate dihydrate tablet-associated gastric lesions. <br>
Methods We retrospectively examined the endoscopic features of 47 patients taking zinc acetate dihydrate tablets who underwent esophagogastroduodenoscopy. <br>
Results Gastric mucosal alterations, including redness, erosions, ulcers, and adhesion of the white coat, were observed in 29 of 47 patients (61.7%). Among patients with gastric lesions (group A), there was a sig-nificantly higher percentage of symptomatic patients in comparison to patients without lesions (group B) (65.5% vs. 22.2%; p<0.01). The background characteristics of the two groups did not differ to a statistically significant extent. On esophagogastroduodenoscopy, mucosal redness (n=27, 93.1%), erosions (n=26, 90.0%), adhesion of the white coat (n=25, 86.2%), and ulcers (n=9, 31.0%) were observed. None of the 19 patients who previously underwent esophagogastroduodenoscopy had gastric lesions before starting zinc acetate dihy-drate. Esophagogastroduodenoscopy was performed after the cessation of zinc acetate dihydrate intake in six patients, and revealed the resolution of gastric lesions. <br>
Conclusion Gastric lesions were observed in 29 of 47 patients who were taking zinc acetate dihydrate tab-lets. The most common endoscopic findings were mucosal redness (93.1%), erosions (90.0%), adhesion of the white coat (86.2%), and ulcers (31.0%). Although the exact pathogenesis is uncertain, we believe that un-derstanding the unique manifestations of this gastric lesion will help physicians manage adverse events in pa-tients taking zinc acetate dihydrate tablets.

kn-title=Verrucous carcinoma of the esophagus with complete response after chemoradiotherapy
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Background : Verrucous carcinoma of the esophagus (VCE) is a rare tumor that is difficult to diagnose. In most cases, biopsies show nonspecific inflammatory and hyperkeratotic changes and do not show malignant findings. Most VCEs are slowly growing, locally advanced tumors with few metastases. Treatments for VCE are the same as for normal esophageal cancer, involving combined chemotherapy, surgical resection, and radiation therapy. However, it has been reported that VCE has a poor response to radiation or chemoradiotherapy (CRT). A case of VCE with complete response (CR) after CRT is presented. <br>
Case presentation : A 70-year-old man was found to have white, irregular esophageal mucosa 4 years earlier. He had been followed up as an outpatient as having candidal esophagitis. However, his tumor grew gradually, and biopsy was performed by endoscopic mucosal resection (EMR). He was finally diagnosed with VCE. He had no metastases to distant organs, but some lymph node metastases were suspected. The tumor invaded his left bronchus. The esophagostomy and gastrostomy were constructed as emergent procedures. The patient then underwent definitive CRT. 4 weeks after the end of CRT, two-stage esophagectomy was performed. First, he underwent esophagectomy with thoracic lymph node dissection. A latissimus dorsi flap was patched to the bronchus after primary suture of the hole. 6 weeks later, reconstruction of the gastric tube was performed through the antethoracic route. The pathological findings showed CR to CRT, with no proliferative cancer cells in the specimen. The patient has had no recurrence for three and half years after the resection. <br>
Conclusions : We presented a locally advanced VCE that achieved CR to CRT. In cases that have some difficulty for local resection, CRT might be an appropriate treatment for VCE.

en-subtitle=

kn-abstract=Data regarding the in-depth surface marker profiles of gastric tissue-resident lymphocytes in autoimmune and Helicobacter pylori-associated gastritis are lacking. In this study, we investigated potential differences in lymphocyte composition between these profiles. We enrolled patients with autoimmune (n = 14), active (current infection of H. pylori in the stomach; n = 10), and inactive gastritis (post-eradication of H. pylori; n = 20). Lymphocytes were isolated from the greater curvature of the stomach and lesser curvature of the body and analyzed using flow cytometry. The CD8(+)/CD3(+) and CD4(+)/CD3(+) ratios differed between the samples. Body CD4(+)/antrum CD4(+), which is calculated by dividing the CD4(+)/CD3(+) ratio in the body by that in the antrum, was significantly higher in autoimmune gastritis (3.54 +/- 3.13) than in active (1.47 +/- 0.41) and inactive gastritis (1.42 +/- 0.77). Antrum CD8(+)/CD4(+) in autoimmune gastritis (7.86 +/- 7.23) was also higher than that in active (1.49 +/- 0.58) and inactive gastritis (2.84 +/- 2.17). The area under the receiver operating characteristic curve of antrum CD8(+)/CD4(+) was 0.842, and the corresponding optimal cutoff point was 4.0, with a sensitivity of 71.4% and a specificity of 93.3%. We propose that an antrum CD8(+)/CD4(+) ratio > 4.0 is a potential diagnostic marker for autoimmune gastritis.

kn-title=Endoscopic features of oxyntic gland adenoma and gastric adenocarcinoma of the fundic gland type differ between patients with and without Helicobacter pylori infection: a retrospective observational study
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Background The endoscopic features of oxyntic gland adenoma and gastric adenocarcinoma of the fundic gland type have not been fully investigated in relation to Helicobacter pylori infection status. We compared the morphology, color, and location of these lesions between patients with and without H. pylori infection. Methods We retrospectively enrolled 165 patients (180 lesions) from 10 institutions. We divided the patients into the (i) Hp group (patients with current H. pylori infection [active gastritis, n = 13] and those with past infection [inactive gastritis, n = 76]) and (ii) uninfected group (H. pylori-uninfected patients, n = 52). We compared the clinical and endoscopic features of the two groups. We also performed an analysis between (i) lesions with atrophy of the surrounding gastric mucosa (atrophy group) and (ii) lesions without atrophy of the surrounding gastric mucosa (non-atrophy group). Results The average age was older in the Hp group than in the uninfected group (68.1 +/- 8.1 vs. 63.4 +/- 8.7 years, p < 0.01). Although the difference was not statistically significant (p = 0.09), multiple lesions were observed in 9 of 89 patients (10.1%) in the Hp group and in only 1 of 52 patients (1.9%) in the uninfected group. Meanwhile, significant differences were observed in the prevalence of lesions located in the gastric fornix or cardia (uninfected group: 67.3% vs. Hp group: 38.0%, p < 0.01), with an elevated morphology (80.0% vs. 56.0%, p < 0.01), with a subepithelial-like appearance (78.2% vs. 42.0%, p < 0.01), and with a color similar to that of the peripheral mucosa (43.6% vs. 25.0%, p = 0.02). The male-to-female ratio, lesion size, and presence or absence of vascular dilatation or black pigmentation on the surface were not different between the two groups. In the analysis comparing lesions with and without mucosal atrophy, the prevalence of multiple lesions was significantly higher (p = 0.02) in the atrophy group (5/25 patients, 20.0%) than in the non-atrophy group (7/141 patients, 5.0%). Conclusions The endoscopic features of oxyntic gland adenoma and gastric adenocarcinoma of the fundic gland type differ between patients with and without H. pylori infection.

kn-title=Clinicopathological Characteristics of Superficial Barrett's Adenocarcinoma in a Japanese Population: A Retrospective, Multicenter Study
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Objective Although Barrett's adenocarcinoma (BA) remains a minor disease in Japan, its incidence has been gradually increasing. We analyzed the characteristics of BA in Japanese populations. <br>
Methods We retrospectively reviewed medical records and analyzed the clinicopathological differences between short-segment Barrett's esophagus (SSBE) and long-segment Barrett's esophagus (LSBE), as well as metastasis. Local recurrence and metachronous lesions were analyzed only in patients who underwent endoscopic resection (ER). <br>
Patients Consecutive patients who had pathological T1 BAs resected by ER or surgery from January 2003 <br>
Results A total of 168 patients were analyzed, including 139 with SSBE and 29 with LSBE. In total, 67% of the SSBE lesions and 32% of the LSBE lesions were located between 0 and 3 o'clock (p=0.0014). No patients who achieved pathological margin-free resection (pR0) and 17% of patients who did not achieve pR0 experienced local recurrence (p=0.0131). None of the patients without lymphovascular involvement, a poorly differentiated component, lesion size of >30 mm, and submucosal invasion of >500 mu m experienced metastasis. The 5-year cumulative incidence rate of metachronous BA after ER was 0% in patients with SSBE and 40% in patients with LSBE (p=0.0005). <br>
Conclusion Superficial BA was likely to be detected at the right anterior wall of SSBE in the Japanese population. The risk for metachronous BA after ER was high in Japanese patients with LSBE, as in Western patients.

kn-title=COVID-19 mRNA Vaccine?Associated Uveitis Leading to Diagnosis of Sarcoidosis: Case Report and Review of Literature
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=<jats:p> A 34-year-old Japanese person with male gender identity who had been taking intramuscular injection of methyltestosterone depot for 11 years after bilateral mastectomy noticed blurred vision 5 days after the second vaccination for COVID-19 (Tozinameran; Pfizer-BioNTech) in the interval of 3 weeks following the first vaccination. The patient was diagnosed as granulomatous iritis with mutton-fat keratic precipitates and small iris nodules at the pupillary margin in the right eye and began to have 0.1% betamethasone eye drops with good response. The patient, however, continued to have fever and malaise and showed a high level of serum soluble interleukin-2 receptor (sIL-2R) even 4 weeks after the second vaccination. Computed tomographic scan disclosed mediastinal and bilateral hilar small lymphadenopathy together with limited granular lesion in the right lung. Gallium-67 scintigraphy demonstrated high uptake not only in mediastinal and hilar lymph nodes but also in bilateral parotid glands. Right parotid gland biopsy revealed noncaseating granulomas and proved pathological diagnosis of sarcoidosis. The systemic symptoms were relieved by oral prednisolone 20 mg daily. Even though the causal relationship remains undetermined, this case is unique at the point that vaccine-associated uveitis led to the detection of pulmonary lesions and lymphadenopathy, resulting in clinical and pathological diagnosis of sarcoidosis. In literature review, 3 patients showed sarcoidosis-like diseases after COVID-19 vaccination: 2 patients were diagnosed clinically as Lofgren syndrome with acute onset of erythema nodosum and ankle swelling, with or without mediastinal and hilar lymphadenopathy, whereas 1 patient with mediastinal lymphadenopathy but no uveitis was diagnosed pathologically by biopsy as sarcoidosis. </jats:p>

en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Objective The rare incidence of submucosal invasive non-ampullary duodenal carcinoma has led to scant information in literature; therefore, we compared the clinicopathological features between submucosal invasive carcinoma (SM-Ca), mucosal carcinoma (M-Ca), and advanced carcinoma (Ad-Ca). Materials We retrospectively analyzed 165 patients with sporadic non-ampullary duodenal carcinomas (SNADCs) from four institutions between January 2003 and December 2018. The SNADCs were divided to three groups according to histological diagnosis: SM-Ca, M-Ca, and Ad-Ca. The clinicopathological characteristics and mucin phenotypes were compared between groups. Results Among the 165 SNADCs, 11 (7%) were classified as SM-Ca, 70 (42%) as M-Ca, and 84 (51%) as Ad-Ca. We found that all SM-Ca (P = 0.013) and most Ad-Ca (P = 0.020) lesions were located on the oral-Vater; however, an almost equal distribution of M-Ca lesions was found between the oral- and anal-Vater. No significant difference was observed between the tumor diameter of M-Ca and SM-Ca; however, 45% (5/11) of SM-Ca were <= 10 mm. A total of 73% (8/11) of SM-Ca were classified as gastric phenotype and no lesions were classified as intestinal phenotype; whereas most M-Ca were classified as intestinal phenotype (67%, 8/12). Conclusions SM-Ca lesions were all located on the oral-Vater and were highly associated with the gastric mucin phenotype, which were different from the features of most M-Ca.

kn-abstract=　A 70-year-old Japanese man underwent esophagogastroduodenoscopy that revealed multiple whitish duodenal granules. The histopathological analysis of the biopsied specimen led to the diagnosis of duodenal-type follicular lymphoma. The lesion showed spontaneous improvement ; however, 14 months later a few small whitish granules were observed by esophagogastroduodenoscopy. Observation under magnification revealed slightly elevated opaque white spots and whitish granular protrusions of roughly the same size that were uniformly distributed in the duodenal bulb. The duodenal bulb lesions were histopathologically diagnosed as lymphoid hyperplasia. The patient also exhibited lymphangiectasia (which presented as scattered white spots) and lymphangioma (which presented as a soft submucosal tumor with white spots on the surface) in the second portion of the duodenum. This patient presented with four white lesions in the duodenum : duodenal-type follicular lymphoma, lymphoid hyperplasia, lymphangiectasia, and lymphangioma. Careful endoscopic evaluation enabled a prompt diagnosis in this case.

kn-abstract=Objectives To investigate the distinctive features of lymphocytes promoting inflammation in ulcerative colitis. Methods We performed flow cytometric analysis of peripheral blood mononuclear cells (PBMCs) and colorectal mucosa lymphocytes in ulcerative colitis patients (n = 13) and control patients (n = 5). Results CD62L(+)/CD3(+)CD4(+) (35.7 +/- 14.0% vs. 19.9 +/- 6.4%) and CD62L(+)/CD3(+)CD4(-) cells (17.1 +/- 17.4% vs. 2.4 +/- 3.9%) were higher in the rectum of ulcerative colitis patients than in control patients. Subpopulation analysis revealed that CD45RA(-)CD62L(+)/CD3(+)CD4(+), that is, central memory T cell fraction in CD4(+) T cells, was significantly increased in the rectum of ulcerative colitis, compared to that in control patients (23.3 +/- 10.5% vs. 8.2 +/- 4.0%). Comparison of rectum and colon samples in ulcerative colitis patients indicated that CD56(+)/CD3(+) was decreased in the rectum compared to that in the colon (11.3 +/- 12.5% vs. 21.3 +/- 16.5%). The ratio of CD56(+)/CD3(+) was also decreased in the rectum of active ulcerative colitis patients compared to that in ulcerative colitis patients at the endoscopic remission stages (2.8 +/- 1.7% vs. 18.5 +/- 13.3%). Conclusion We demonstrated that CD62L(+) T lymphocytes, particularly the CD45RA(-)CD62L(+) T cell subset that represents central memory T cells, were increased in the rectum of patients with ulcerative colitis. In addition, the CD56(+)/CD3(+) subset (natural killer T cells) was decreased in the rectum compared to that of less inflamed colonic mucosa. These results suggest that the enrichment of central memory T lymphocytes and the reduction of natural killer T cells in the gut mucosa are involved in the pathogenesis of ulcerative colitis.

kn-title=Diffuse Large B-Cell Lymphoma 18 Years After Bilateral Lacrimal Gland IgG4-Related Disease: Case Report and Literature Review
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=IgG4-related disease is a recently established clinical entity. The disease might serve as the background for later development of systemic lymphoma. This study aims to confirm the diagnosis of IgG4-related disease by re-staining lacrimal gland lesions diagnosed previously with low-grade lymphoma in a patient who developed systemic diffuse large B-cell lymphoma (DLBCL) 18 years later. A 53-year-old man developed bilateral lacrimal gland swelling and right submandibular gland swelling and was diagnosed by excision as low-grade lymphoma. In follow-up, positron emission tomography showed high uptake in the median hyoid 11 years later but no malignancy was detected by laryngeal submucosal biopsy. He was well with no treatment until 18 years later when he had palatal swelling and was diagnosed with DLBCL by oral floor biopsy. He had systemic lymphadenopathy, infiltration in paranasal sinuses, hypopharynx, small intestine, kidney, and prostate. He underwent 8 courses of R-CHOP and 3 courses of high-dose methotrexate and achieved complete remission with no relapse for 1 year thereafter. Re-immunostaining of paraffin blocks of bilateral lacrimal gland lesions showed IgG and IgG4-positive lymphocytes and plasma cells among lymphoid follicles separated by fibrous bundles, with 10 or more IgG4-positive cells in high-power field. The IgG4/IgG-positive cell ratio was 100% and the number of κ chain-positive cells and λ chain-positive cells was the same. The bilateral lacrimal lesions were thus re-diagnosed as IgG4-related disease. In conclusion, systemic DLBCL occurred approximately 20 years after lacrimal gland IgG4-related disease. Literature review revealed 12 patients with IgG4-related disease, including the present patient, who later developed lymphoma in the other organs.

kn-abstract=BACKGROUND<br>
It remains unclear which factors, such as tumor volume and tumor invasion, influence circulating tumor DNA (ctDNA), and the origin of ctDNA in liquid biopsy is always problematic. To use liquid biopsies clinically, it will be very important to address these questions.<br>
AIM<br>
To assess the origin of ctDNA, clarify the dynamics of ctDNA levels, assess ctDNA levels by using a xenograft mouse after treatment, and to determine whether tumor volume and invasion are related to ctDNA levels.<br>
METHODS<br>
Tumor xenotransplants were established by inoculating BALB/c-nu/nu mice with the TE11 cell line. Groups of mice were injected with xenografts at two or four sites and sacrificed at the appropriate time point after xenotransplantation for ctDNA analysis. Analysis of ctDNA was performed by droplet digital PCR, using the human telomerase reverse transcriptase (hTERT) gene.<br>
RESULTS<br>
Mice given two-site xenografts were sacrificed for ctDNA at week 4 and week 8. No hTERT was detected at week 4, but it was detected at week 8. However, in four-site xenograft mice, hTERT was detected both at week 4 and week 6. These experiments revealed that both tumor invasion and tumor volume were associated with the detection of ctDNA. In resection experiments, hTERT was detected at resection, but had decreased by 6 h, and was no longer detected 1 and 3 d after resection.CONCLUSIONWe clarified the origin and dynamics of ctDNA, showing that tumor volume is an important factor. We also found that when the tumor was completely resected, ctDNA was absent after one or more days.

kn-title=Bilateral Optic Disc Swelling as a Plausible Common Ocular Sign of Autoinflammatory Diseases: Report of Three Patients with Blau Syndrome or Cryopyrin-Associated Periodic Syndrome
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=The aim of this study is to describe bilateral optic disc swelling in three consecutive patients with Blau syndrome or cryopyrin-associated periodic syndrome at a single institution. Case 1 was a 30-year-old woman receiving 25 mg etanercept twice weekly who had been diagnosed as early-onset sarcoidosis by biopsy of skin rashes at 5 months old and genetically diagnosed with Blau syndrome with CARD15/NOD2 mutation (N670K) at 13 years old. At 10 years old, she began to have uveitis with optic disc swelling in both eyes, resulting in macular degeneration and optic disc atrophy at 17 years old only when etanercept was introduced. Case 2 was a 21-year-old man receiving adalimumab every 2 weeks who had been diagnosed as early-onset sarcoidosis by biopsy of skin rashes at 1.5 years old and genetically diagnosed as Blau syndrome with CARD15/NOD2 mutation (C495Y) at 5 years old. At 8 years old, around the time of adalimumab introduction, he began to show bilateral optic disc swelling which continued until the age of 16 years when the dose of adalimumab was increased. Case 3 was a 20-year-old woman receiving canakinumab every 8 weeks for systemic symptoms such as fever, headache, vomiting, and abdominal pain and later for sensorineural hearing disturbance on both sides. She had been diagnosed genetically with cryopyrin-associated periodic syndrome with NLRP3 mutation (Y859C) at 7 years old. At 5 years old, she was found to have bilateral optic disc swelling, which continued until the age of 10 years when she began receiving canakinumab (IL-1β inhibitor). Bilateral optic disc swelling might be tentatively designated as a plausible common ocular feature, if it occurred, in autoinflammatory diseases to pay more attention to ophthalmic complications in rare diseases.

kn-title=Scoring systems for differentiating gastrointestinal stromal tumors and schwannomas from leiomyomas in the stomach
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=There is no practical predictive model for the diagnosis of gastrointestinal stromal tumors (GISTs). To establish a practical predictive model for the diagnosis of subepithelial lesions in the stomach, we reviewed patients with GISTs (n = 89), schwannomas (n = 7), and leiomyomas (n = 28). The tumor was more frequently found along the gastric cardia in the leiomyoma group (57.1%) than in the GIST/schwannoma group (2.1%, P < .01). Contrast enhancement (57.3% vs 0%, P < .01) and intra-tumoral necrosis (34.4% vs 0.0%, P < .01) were more frequently observed in the GIST/schwannoma group than in the leiomyoma group. On endoscopic ultrasonography, 58.3% of GISTs/schwannomas showed uneven echogenicity, whereas the echogenicity was uneven in 21.4% of leiomyomas (P < .01). There were no differences between the tumor color and the presence or absence of ulcer formation, tumor bleeding, irregularity of the tumor margin, cystic spaces, and hyperechoic spots between the 2 groups. Based on these results, we developed a 2-step diagnostic algorithm for GISTs/schwannomas. The first step comprises 1 endoscopic feature: a cardiac or non-cardiac location. Tumors with a cardiac location were judged as leiomyomas and those with a non-cardiac location were judged as GISTs/schwannomas, with 96.9% sensitivity and 57.1% specificity for GIST/schwannoma diagnosis. The second step comprises a combination of endoscopic (non-cardiac location), radiologic (positive contrast enhancement and intra-tumoral necrosis), and endosonographic (uneven echogenicity) features for a total of 4 points. We assigned 1 point to each feature. Tumors with scores of 2 to 4 were judged as GISTs/schwannomas, with 81.3% sensitivity and 92.9% specificity for GIST/schwannoma diagnosis. Our predictive model will be a practical guide for the management of gastric subepithelial lesions.

kn-title=Proton beam therapy followed by pembrolizumab for giant ocular surface conjunctival malignant melanoma: A case report
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=The present study describes proton beam therapy as a clinical option to achieve local control of giant conjunctival melanoma in an aged person, instead of orbital exenteration. An 80?year?old woman with one?year history of left?eye injection and hemorrhage experienced rapid growth of the ocular surface black mass. At the initial visit, a black, elastic hard, hemorrhage?prone, thickened mass in the size of 30x40 mm with a presumed wide stalk covered the total area of the lid fissure on the left side. Biopsy of the mass demonstrated anomalous melanin?containing cells in fibrin and hemorrhage, which were positive for cocktail?mix antibodies against tyrosinase, melanoma antigen recognized by T cells?1 and human melanoma black?45, indicative of malignant melanoma. One month after the initial visit, the patient underwent proton beam therapy at the total dose of 70.4 Gy (relative biological effectiveness) in 32 fractions (~10 min each) in one and a half months. One month after the end of proton beam therapy, 3.5 months from the initial visit, the patient was found by computed tomographic scan to have multiple metastatic lesions in bilateral lung fields. With the evidence of absent BRAF mutation, the patient underwent intravenous administration of pembrolizumab 77.2 mg every three weeks five times in total. Then, three months after proton beam therapy, ocular surface melanoma almost subsided and the clear cornea allowed visualization of the intraocular lens inside the eye. In three weeks, spontaneous corneal perforation was plugged with iris incarceration. The patient died suddenly of unknown cause 7.5 months from the initial visit. The local control of giant conjunctival melanoma was achieved by proton beam therapy, leading to patient's satisfaction and better quality of life. Proton beam therapy, followed by immune checkpoint inhibitors, would become the future standard of care for unresectable giant conjunctival melanoma.

kn-title=The Impact of KRAS Mutation in Patients With Sporadic Nonampullary Duodenal Epithelial Tumors
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=INTRODUCTION: The genomic characterization of primary nonampullary duodenal adenocarcinoma indicates a genetic resemblance to gastric and colorectal cancers. However, a correlation between the clinical and molecular characteristics of these cancers has not been established. This study aimed to elucidate the clinicopathological features of sporadic nonampullary duodenal epithelial tumors, including their molecular characteristics and prognostic factors. <br>
METHODS: One hundred forty-eight patients with sporadic nonampullary duodenal epithelial tumors were examined in this study. Patient sex, age, TNM stage, tumor location, treatment methods, histology, KRAS mutation, BRAF mutation, Fusobacterium nucleatum, mucin phenotype, and programmed death-ligand 1 (PD-L1) status were evaluated. KRAS and BRAF mutations, Fusobacterium nucleatum, mucin phenotype, and PD-L1 status were analyzed by direct sequencing, quantitative polymerase chain reaction, and immunochemical staining. <br>
RESULTS: The median follow-up duration was 119.4 months. There were no deaths from duodenal adenoma (the primary disease). Kaplan-Meier analysis for duodenal adenocarcinoma showed a significant effect of TNM stage (P < 0.01). In univariate analysis of primary deaths from duodenal adenocarcinoma, TNM stage II or higher, undifferentiated, KRAS mutations, gastric phenotype, intestinal phenotype, and PD-L1 status were significant factors. In multivariate analysis, TNM stage II or higher (hazard ratio: 1.63 x 10(10), 95% confidence interval: 18.66-6.69 x 10(36)) and KRAS mutation (hazard ratio: 3.49, confidence interval: 1.52-7.91) were significant factors. <br>
DISCUSSION: Only KRAS mutation was a significant prognostic factor in primary sporadic nonampullary duodenal adenocarcinoma in cases in which TNM stage was considered.

kn-title=Clinical characteristics and course of sporadic non-ampullary duodenal adenomas A multicenter retrospective study
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Sporadic non-ampullary duodenal adenoma (SNADA) is a rare disease, and therefore, its clinical characteristics have not been comprehensively investigated. Furthermore, owing to the high complication rates and severity of endoscopic resection, treatment strategies vary among facilities. In the present study, we aimed to clarify the clinical characteristics and course of SNADA. We extracted clinical and histological records of SNADA cases diagnosed in 11 hospitals between September 1999 and August 2014. The patients were divided into "no-resection" and "resection" groups based on the initial treatment approach. We investigated the long-term outcome of the "no-resection" group and treatment results of the "resection" group, with particular interest in endoscopic resection. Overall, 299 patients were diagnosed with SNADA. The median age at diagnosis was 67 years (range, 31-88 years), with approximately twice as many men as women. The median tumor size was 8.0 mm (2-60 mm). In total, 161 patients were initially selected for no-resection and 138 underwent resection. Age >70 years and the presence of either severe illness or poor performance status were significantly related to opting for no-resection. In the no-resection group, 101 patients underwent endoscopic follow-up for at least 1 year. During the observational period (2.5 +/- 2.2 years), 27 lesions (27%) disappeared following cold forceps biopsy, and 13 lesions (14%) presented lateral growth. Four lesions (4%) changed to mucosal carcinoma, 3 were treated endoscopically, and 1 was surgically resected. Nineteen patients died; however, no one died of duodenal carcinoma. In the endoscopic resection group, en bloc resection was achieved in 78% of patients. However, the complication rate for perforation was 7%, and endoscopic submucosal dissection was associated with a 36% perforation rate. With the low incidence of cancer development and no disease specific death, the strategy of initially not performing resection could be considered especially for the older adults, poor-prognosis patients, or small lesions.

kn-title=Squamous Metaplasia of the Stomach Associated with Lymphoma Infiltration
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=We herein report a patient who presented with follicular lymphoma. Although the stomach was initially intact, mucosal redness and multiple erosions appeared in the gastric body owing to infiltration of the follicular lymphoma cells. Subsequently, a slightly depressed, white area lacking gastric mucosal structure was detected in the lesser curvature of the gastric cardia and body, where lymphoma cell infiltration was also pathologically observed beneath the stratified squamous epithelium. This case indicated that, although infrequent, prolonged mucosal injury owing to lymphoma infiltration can cause squamous metaplasia in the stomach.

kn-abstract=Leucine-rich alpha-2 glycoprotein (LRG) may be a novel serum biomarker for patients with inflammatory bowel disease. The association of LRG with the endoscopic activity and predictability of mucosal healing (MH) was determined and compared with those of C-reactive protein (CRP) and fecal markers (fecal immunochemical test [FIT] and fecal calprotectin [Fcal]) in 166 ulcerative colitis (UC) and 56 Crohn's disease (CD) patients. In UC, LRG was correlated with the endoscopic activity and could predict MH, but the performance was not superior to that of fecal markers (areas under the curve [AUCs] for predicting MH: LRG: 0.61, CRP: 0.59, FIT: 0.75, and Fcal: 0.72). In CD, the performance of LRG was equivalent to that of CRP and Fcal (AUCs for predicting MH: LRG: 0.82, CRP: 0.82, FIT: 0.70, and Fcal: 0.88). LRG was able to discriminate patients with MH from those with endoscopic activity among UC and CD patients with normal CRP levels. LRG was associated with endoscopic activity and could predict MH in both UC and CD patients. It may be particularly useful in CD.

kn-title=Prostate Cancer Detected by Choroidal Tumor and Complete Response to Hormonal Therapy: Case Report and Literature Review of 24 Patients With Choroidal Metastasis From Prostate Cancer
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Metastatic choroidal tumors derived from prostate cancer are rare. In this study, we report a patient who manifested a choroidal tumor as the initial presenting sign of prostate cancer and review 23 patients with choroidal metastasis of prostate cancer in the literature to answer a clinical question how the choroidal metastases would respond to hormonal therapy. A 73-year-old man presented with a choroidal tumor in the right eye. He was in good health and had no previous history except for current hemodialysis in 3 years due to chronic renal failure as a sequel to glomerulonephritis. With the diagnosis of a probable metastatic tumor, positron emission tomography was performed to disclose high-uptake sites in multiple bones, lymph nodes, and the prostate, together with multiple nodular lesions in bilateral lungs on computed tomography (CT) scan. Serum prostate-specific antigen (PSA) was elevated to 541 ng/mL, which supported prostate cancer as the primary site. He had degarelix injection, and the choroidal tumor resolved rapidly and became flat degeneration in a month. Prostate biopsy showed poorly differentiated adenocarcinoma, and he underwent surgical castration. He had no medication until 3 years later when he showed gradual increase of serum PSA up to 6.05 ng/mL and multiple bony metastases on CT scan. Bicalutamide, switched to enzalutamide and then to abiraterone, led to the undetectable level of serum PSA until the last visit with no relapse of the choroidal metastasis, 6.8 years after the initial visit. In the literature review of 24 patients with choroidal metastasis of prostate cancer, including this patient, 8 patients presented a choroidal tumor as the initial sign and the choroidal lesions mostly showed complete response to hormonal therapy. Among 13 patients who were frequently in the course of hormonal therapy, choroidal metastases showed complete or partial response to external beam radiation to the eye in 11 patients and episcleral plaque radiotherapy in 2 patients. In conclusion, metastatic choroidal tumors of prostate cancer would show good response to hormonal therapy when the therapy has not been initiated. Hormone-resistant choroidal metastases in the therapeutic course of prostate cancer could be managed successfully by external beam radiation to the eye.

kn-title=Two Cases of Endometriosis in the Cecum Detected by Contrast-enhanced Computed Tomography with Air/Carbon Dioxide Insufflation
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=We herein report two patients with endometriosis in the cecum. Both patients presented with a protruding, subepithelial tumor on colonoscopy and were diagnosed with cecal endometriosis after surgical resection. It is notable that the cecal lesions were not initially identified on computed tomography (CT), while CT colonography with air/carbon dioxide insufflation resulted in the detection of the cecal tumor. These cases highlight the possibility of false-negative results on conventional CT in patients with cecal endometriosis. We consider CT colonography with air/carbon dioxide insufflation useful for detecting cecal tumors in such cases.

kn-title=Long-term survival without recurrence after surgery for gastric yolk sac tumor-like carcinoma: a case report
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Background Gastric yolk sac tumor (YST)-like carcinoma is extremely rare, and its prognosis is poor, because most patients have widespread metastases at the time of diagnosis. We report a case of gastric YST-like carcinoma with an adenocarcinoma component without metastases in which curative resection was performed. Case presentation A 77-year-old man complaining of melena and dizziness due to anemia was diagnosed with poorly differentiated adenocarcinoma in the gastric cardia, with a benign ulcer in the gastric body. He underwent total gastrectomy with D2 lymph node dissection for the tumor. Histological examination of the resected specimens revealed a mixture of reticular and glandular neoplastic components morphologically. In the reticular area, an endodermal sinus pattern and some Schiller-Duval bodies were confirmed. Gastric YST-like carcinoma with adenocarcinoma components, T2N0M0 Stage IB, was diagnosed. Immunohistochemical analysis showed that the YST was positive for carcinoembryonic antigen (CEA), alpha-fetoprotein (AFP) and p53. In contrast, the adenocarcinoma was positive for p53 and negative for CEA and AFP. The patient remained healthy as of 7 years postoperatively, with no recurrence. Conclusions Routine medical examinations or endoscopic examinations for accidental symptom may be helpful for early diagnosis and good prognosis for gastric YST-like carcinoma, although the prognosis is generally poor.

kn-title=Risk Factors for Gastric Cancer after the Eradication of Helicobacter pylori Evaluated Based on the Background Gastric Mucosa: A Propensity Score-matched Case-control Study
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Objective<br> The eradication of Helicobacter pylori (H. pylori) reduces the risk for gastric cancer (GC) development, but it cannot prevent GC completely. We investigated the risk factors of early GC development after the eradication of H. pylori, based on the histological characteristics of gastric mucosa. <br><br>
Methods<br> Sixty-one patients who underwent endoscopic submucosal dissection for early GC after successful H. pylori eradication (Group A) and 122 patients without developing a gastric neoplasm over 3 years after successful H. pylori eradication (Group B) were analyzed. We compared the histological findings of the patients enrolled in Group A and Group B before and after the propensity score-matching.<br><br>
Results<br> Comparing the characteristics of two the groups, Group A consisted predominantly of males, had significantly more elderly patients, and the years after successful eradication tended to be longer. We performed score matching for these three factors to reduce the influence of any confounding factors. After matching, the scores of inflammation for Group A (n=54) was significantly higher than those of Group B (n =54) at the greater curvature of the antrum, the lesser curvature of the corpus, and the greater curvature of the corpus. According to a multivariate analysis, inflammation of the greater curvature of the antrum and lesser curvature of the corpus were found to be independent risk factors. The risk ratio and 95% CI were 5.92 (2.11-16.6) (p<0.01), and 3.56 (1.05-13.2) (p=0.04), respectively.<br><br>
Conclusion<br>A continuous high level of inflammation of the background gastric mucosa may he a risk factor for gastric cancer onset after H. pylori eradication.

kn-title=Endoscopic ultrasonography findings of pancreatic parenchyma for predicting subtypes of intraductal papillary mucinous neoplasms
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Background and Aims:<br>
 The subtypes of intraductal papillary mucinous neoplasms (IPMNs) are closely associated with the clinicopathological behavior and recurrence after surgical resection. However, there are no established non-invasive methods to confirm the subtypes of IPMNs without surgery. The aim of this study is to predict the subtypes of IPMNs using the findings of endoscopic ultrasonography (EUS). <br>
<br>
Methods:<br>
Sixty-two consecutive patients with IPMNs who underwent EUS before surgery were retrospectively reviewed. The following EUS findings were analyzed and their relationship with the subtypes was evaluated: diameter of the main pancreatic duct, cyst size, number of cysts, height of mural nodule, early chronic pancreatitis (CP) finding, fatty parenchyma and atrophic parenchyma.<br>
<br>
Results:<br>
The subtypes of IPMNs were as follows: gastric (G)-type 38 (61%), intestinal (I) -type 14 (23%) and pancreatobiliary (PB) -type 10 (16%). Fatty parenchyma was significantly associated with G-type (P < 0.0001). Early CP findings ? 2 and atrophic parenchyma were significantly correlated with I-type (P < 0.0001). PB-type was significantly associated with pancreatic parenchyma without early CP findings or fatty degeneration in comparison to the other subtypes (P < 0.0001). Using the above characteristic EUS findings, the sensitivity, specificity, and accuracy were as follows: 63%, 92% and 74%, respectively, in G-type, 57%, 96% and 87% in I-type, and 90%, 94% and 94% in PB-type.<br>
<br>
Conclusions:<br>
The evaluation of EUS findings, especially focused on the pancreatic parenchyma, has the potential to predict the subtypes of IPMN.

kn-title=Gastric Adenoma: A High Incidence Rate of Developing Carcinoma and Risk of Metachronous Gastric Cancer according to Long-Term Follow-Up
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Introduction:<br>
Gastric adenomas are histologically defined as benign epithelial tumors. While some of them remain adenomas for a long time, others progress to carcinomas. However, long-term outcomes of such cases are not entirely clear. Here, we explored the risk factors and incidence of developing carcinoma from gastric adenoma as well as metachronous gastric cancer.<br>
Methods:<br>
This study was conducted at a facility that adopted a follow-up strategy for gastric adenoma. Lesions histologically diagnosed as gastric intestinal-type adenomas between January 2004 and December 2016 were analyzed. Clinicopathological data were collected from patients’ medical records, and histological changes from adenoma to carcinoma during endoscopic follow-up and risk factors of cancer development were evaluated.<br>
Results:<br>
This study involved 409 lesions from 376 patients. The analysis of the development of gastric cancer from adenoma and metachronous gastric cancer was ultimately performed for 282 lesions from 258 patients and 269 lesions from 246 patients, respectively, due to different follow-up periods. The 5-year rate of carcinoma development was 34.0%. Risk factors for carcinoma development upon multivariate analysis were lesion size ?15 mm and morphological depression. All cases with both factors developed gastric carcinoma, and 50.5% of those with either factor developed carcinoma within 5 years. Gastric adenoma was accompanied by metachronous gastric cancer in 1.5% of the patients annually. The only risk factor for metachronous gastric carcinoma was primary adenoma progressing to carcinoma during the follow-up period.<br>
Discussion/Conclusion:<br>
Given the high rate of carcinoma development in patients with risk factors, resection of gastric adenoma should be considered during the initial examination. Careful observation and follow-up should also be conducted to detect not only changes in the primary adenoma but also the occurrence of metachronous carcinoma, especially in cases of adenoma progressing to carcinoma.

kn-abstract=The aim of this study was to reveal the histological features of oxyntic gland adenomas and gastric adenocarcinoma of the fundic-gland type (GA-FG). We retrospectively examined the histological features of 126 lesions of oxyntic gland adenoma and/or GA-FG in 116 patients. The prevalence of oxyntic gland adenomas and GA-FG was approximately equal. The majority of the lesions were resected by endoscopic mucosal resection using a diathermic snare (EMR, n=42) or endoscopic submucosal dissection (ESD, n=72). Histologically, there were no lesions with invasion at the level of the muscularis propria or deeper, and lymphovascular invasion was present in 1.6%. Of the ESD and EMR specimens, there were no lesions that were positive for vertical margins. Among the eight GA-FG patients with deep (>= 500 mu m) submucosal invasion, six were treated with endoscopic resection alone, and no recurrence was documented. No patients died of the disease during the median follow-up period of 14.5 months. In conclusion, all lesions were confined to the mucosa or submucosa and were negative for vertical margins. Lymphovascular invasion was present in only 1.6% of the patients. Thus, we believe that endoscopic resection is a suitable initial treatment method for oxyntic gland adenoma and GA-FG.

kn-abstract=Targeted therapies for malignant melanoma have improved patients’ prognoses. A primary gastrointestinal malignant melanoma is very rare, with no standard treatment strategy. We treated a 78-year-old Japanese female with advanced primary gastrointestinal melanoma of the descending colon and gallbladder. We administered a multidisciplinary treatment: surgical resection of the descending colon and gallbladder tumors, resection of the metastatic lymph nodes behind the pancreas head, and immune checkpoint antibody-blockade therapy (nivolumab) for ~4 years. PET/CT demonstrated no recurrent lesion for > 3 years.  Multidisciplinary therapies (e.g., surgery, chemotherapy, radiotherapy, target therapy, and immune checkpoint antibody-blockade therapy) can successfully treat primary gastrointestinal malignant melanoma.

kn-title=Efficacy and safety of endoscopic submucosal dissection for gastric tube cancer: A multicenter retrospective study
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=BACKGROUND Recent improvements in the prognosis of patients with esophageal cancer have led to the increased occurrence of gastric tube cancer (GTC) in the reconstructed gastric tube. However, there are few reports on the treatment results of endoscopic submucosal dissection (ESD) for GTC. AIM To evaluate the efficacy and safety of ESD for GTC after esophagectomy in a multicenter trial. METHODS We retrospectively investigated 48 GTC lesions in 38 consecutive patients with GTC in the reconstructed gastric tube after esophagectomy who had undergone ESD between January 2005 and December 2019 at 8 institutions participating in the Okayama Gut Study group. The clinical indications of ESD for early gastric cancer were similarly applied for GTC after esophagectomy. ESD specimens were evaluated in 2-mm slices according to the Japanese Classification of Gastric Carcinoma with curability assessments divided into curative and non-curative resection based on the Gastric Cancer Treatment Guidelines. Patient characteristics, treatment results, clinical course, and treatment outcomes were analyzed. RESULTS The median age of patients was 71.5 years (range, 57-84years), and there were 34 men and 4 women. The median observation period after ESD was 884 d (range, 8-4040 d). The median procedure time was 81 min (range, 29-334 min), the en bloc resection rate was 91.7% (44/48), and the curative resection rate was 79% (38/48). Complications during ESD were seen in 4% (2/48) of case, and those after ESD were seen in 10% (5/48) of case. The survival rate at 5 years was 59.5%. During the observation period after ESD, 10 patients died of other diseases. Although there were differences in the procedure time between institutions, a multivariate analysis showed that tumor size was the only factor associated with prolonged procedure time. CONCLUSION ESD for GTC after esophagectomy was shown to be safe and effective.

kn-abstract=In this report, we describe a patient with myoepithelial hamartoma, which is regarded as synonymous with adenomyosis and heterotopic pancreas. Endoscopy revealed a submucosal tumor in the antrum of the stomach. Subsequently, distal gastrectomy with Roux-en-Y reconstruction was performed. Histological findings of adenomyomatous lesion and heterotopic pancreatic tissue were observed in this lesion. The distribution of OCT4, which is a pluripotency marker, varied in each part.

en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=The diagnostic criteria for IgG4-related disease were previously published and serum IgG4 measurement has been reimbursed by national health insurance in Japan since 2012. Eight patients diagnosed with IgG4-related disease based on lacrimal gland masses were retrospectively reviewed. The 8 patients were 3 men and 5 women ranging in age from 52 to 77 (median, 63) years at the initial visit and their follow-up period ranged from 0.25 to 11 (median, 7) years. Bilateral and unilateral involvement were noted in 4 patients each; 2 on the right side and 2 on the left side in those with unilateral involvement. Serum IgG4 was high in 5 of 8 patients at the initial visit. Five patients with no systemic signs were followed without treatment, whereas oral steroids were administered and tapered in the other 3 patients who exhibited systemic signs. One patient with a history of radiation for MALT lymphoma in bilateral lacrimal glands developed IgG4-related disease in the left lacrimal gland 10 years later and was followed without treatment. Nine years later, her serum IgG4 level increased to 1500 mg/dL and paracardiac lesions, found on positron emission tomography, were confirmed to be MALT lymphoma by needle biopsy, leading to systemic chemotherapy. The other 7 patients had neither local recurrence nor additional systemic signs. Serum IgG4 monitoring may be useful to detect systemic complications in IgG4-related ophthalmic disease and markedly high serum IgG4 levels may indicate new lymphoma at other sites.

kn-abstract=Chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) accounts for approximately 1% of all lymphomas in our department. In this article, we describe the differential diagnosis of CLL/SLL from other indolent lymphomas, with special reference to follicular lymphoma, marginal zone B-cell lymphoma, lymphoplasmacytic lymphoma, and mantle cell lymphoma, although the latter is considered to be aggressive. CLL/SLL often exhibits proliferation centers, similar to follicular lymphoma. Immunohistological examination can easily distinguish these two lymphomas. The most important characteristic of CLL/SLL is CD5 and CD23 positivity. Mantle cell lymphoma is also CD5-positive and there are some CD23-positive cases. Such cases should be carefully distinguished from CLL/SLL. Some marginal zone lymphomas are also positive for CD5 and such cases are often disseminated. Lymphoplasmacytic lymphoma should also be a differential diagnosis for CLL/SLL. It frequently demonstrates MYD88 L265P, which is a key differential finding. By immunohistological examination, the expression of lymphoid enhancer-binding factor 1 is specific for CLL/SLL and can be a good marker in the differential diagnosis.

kn-title=Observer agreement for the diagnosis of intestinal acute graft?vs.?host disease based on the presence of villous atrophy in the terminal ileum
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Intestinal graft?vs.?host disease (GVHD) is a serious complication of allo?hematopoietic stem cell transplantation (allo?HSCT). Villous atrophy in the terminal ileum is considered a useful diagnostic indicator for GVHD. However, the inter? and intra?observer agreement regarding the ileocolonoscopic findings indicative of acute intestinal GVHD, i.e., villous atrophy in the terminal ileum, are currently insufficient in multiple institutions. Thus, the present study aimed to investigate the incidence of villous atrophy in the terminal ileum to diagnose acute intestinal GVHD and determine the inter? and intra?observer agreement regarding this result for experienced endoscopists from multiple institutions. Consecutive patients who underwent allo?HSCT were referred to our institution between May 2008 and September 2015. A total of 54 patients underwent total ileocolonoscopy after allo?HSCT due to suspected intestinal acute GVHD. Subsequently, three observers from different institutions evaluated the cases for the presence of villous atrophy in the terminal ileum. In this study, the pathology results were a gold standard to evaluate the predictive value of ileocolonoscopy detection. Definitive pathological and non?pathological GVHD was diagnosed in 22 and 32 cases, respectively. The results of examining whether villous atrophy could predict GVHD were as follows. For three observers (A, B and C), the sensitivity of villous atrophy in the terminal ileum was 86.4, 77.3 and 79.2%, respectively, whereas the specificity was 62.5, 62.5 and 86.7%, respectively. The positive predictive value (PPV) and negative predictive value (NPV) of villous atrophy for GVHD were as follows: The PPV of appearance was 61.3, 58.6 and 82.6%, respectively, whereas the NPV was 87.0, 80.0 and 83.9%, respectively. Kappa coefficients for the inter?observer reliability were 0.85, 0.63 and 0.63 for observers A and B, A and C, and B and C, respectively. The intra?observer kappa coefficient was 0.88 for observer A, 0.73 for observer B and 0.75 for observer C. A substantial observer agreement was achieved for the analysis of villous atrophy in the terminal ileum and the agreement for the predictive histological diagnosis was also excellent. Based on the results of the present study, identification of villous atrophy in the terminal ileum was a clinically effective diagnostic parameter, even if different endoscopists were involved in the diagnosis at multiple institutions. The present study was registered as a trial with the University Hospital Medical Information Network (UMIN; registration no. UMIN000025390).

kn-title=Review of the diagnosis of gastrointestinal lanthanum deposition
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Lanthanum carbonate is used for treatment of hyperphosphatemia mostly in patients with chronic renal failure. Although lanthanum carbonate is safe, recently, lanthanum deposition in the gastrointestinal mucosa of patients has been reported in the literature. This review provides an overview of gastroduodenal lanthanum deposition and focuses on disease’s endoscopic, radiological, and histological features, prevalence, and outcome, by reviewing relevant clinical studies, case reports, and basic research findings, to better understand the endoscopic manifestation of gastrointestinal lanthanum deposition. The possible relationship between gastric lanthanum deposition pattern and gastric mucosal atrophy is also illustrated; in patients without gastric mucosal atrophy, gastric lanthanum deposition appears as diffuse white lesions in the posterior wall and lesser curvature of the gastric body. In the gastric mucosa with atrophy, lanthanum-related lesions likely appear as annular or granular whitish lesions. Moreover, these white lesions are probably more frequently observed in the lower part of the stomach, where intestinal metaplasia begins.

en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=A 64-year-old Japanese man suffered cardiopulmonary arrest, which may have resulted from sepsis and/or hyperosmolar hyperglycemic non-ketonic coma, and was admitted after successful resuscitation. He had watery diarrhea on day 18 and was diagnosed with cytomegalovirus enterocolitis. In addition, computed tomography performed on day 27 and colonoscopy revealed gastric emphysema and intestinal pseudolipomatosis, respectively. This report is the first to describe a patient with cytomegalovirus enterocolitis and subsequent gastric emphysema and pseudolipomatosis. Gastrointestinal cytomegalovirus infection may underlie gastric emphysema and intestinal pseudolipomatosis, particularly in patients with relative or obvious immune dysfunction.

kn-title=Four Cases of Desquamative Esophagitis Occurring after Hematopoietic Stem Cell Transplantation
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=We herein report four patients with desquamative esophagitis that developed one to nine days after peripheral blood stem cell transplantation (PBSCT). Three patients underwent allogeneic PBSCT for leukemia, and the other underwent autologous PBSCT for pineoblastoma. Esophagogastroduodenoscopy revealed mucosal sloughing and fresh blood in the esophagus. Fasting and intravenous proton pump inhibitor therapy in addition to blood transfusion improved the esophageal lesions within five to seven days in three patients. These cases indicate that desquamative esophagitis can occur in patients who receive hematopoietic stem cell transplantation. Although blood transfusions may be required, it can be resolved within seven days.

en-abstract=
kn-abstract=Background</br>
It is often difficult to diagnose inflammatory bowel disease (IBD)-associated neoplasia endoscopically due to background inflammation. In addition, due to the absence of sensitive tumor biomarkers, countermeasures against IBD-associated neoplasia are crucial. The purpose of this study is to develop a new diagnostic method through the application of liquid biopsy.</br>
Methods</br>
Ten patients with IBD-associated cancers and high-grade dysplasia (HGD) with preserved tumor tissue and blood were included. Tumor and non-tumor tissues were analyzed for 48 cancer-related genes using next-generation sequencing. Simultaneously, circulating tumor DNA (ctDNA) was analyzed for mutations in the target genes using digital PCR.</br>
Results</br>
Out of 10 patients, seven had IBD-related cancer and three had IBD-related HGD. Two patients had carcinoma in situ; moreover, three had stageII and two had stage III. To avoid false positives, the mutation rate cutoff was set at 5% based on the control results; seven of 10 (70%) tumor tissue samples were mutation-positive. Mutation frequencies for each gene were as follows: TP53 (20.9%; R136H), TP53 (25.0%; C110W), TP53 (8.5%; H140Q), TP53 (31.1%; R150W), TP53 (12.8%; R141H), KRAS (40.0%; G12V), and PIK3CA (34.1%; R 88Q). The same mutations were detected in the blood of these seven patients. However, no mutations were detected in the blood of the remaining three patients with no tumor tissue mutations. The concordance rate between tumor tissue DNA and blood ctDNA was 100%.</br>
Conclusion</br>
Blood liquid biopsy has the potential to be a new method for non-invasive diagnosis of IBD-associated neoplasia.

kn-abstract=In this paper, we introduce a simplified, one-step procedure for lymphocyte isolation from an endoscopically biopsied fragment. For lymphocyte isolation, an endoscopically harvested specimen and 5 mL of normal saline solution were placed in a wire mesh strainer set in a porcelain bowl. To obtain the lymphocyte suspension, the solid specimen was crushed using the rubber portion of a plunger of a 10 mL injection syringe. Flow cytometry was performed using the lymphocyte suspension. For validating our methods, the one-step lymphocyte isolation technique was used to perform flow cytometry on samples from 23 patients with (n = 12) or without (n = 11) gastrointestinal lymphoma. Flow cytometry of light chain expression was performed in all patient samples (feasibility: 100%). Sensitivity was 83.3% (10/12) and specificity was 100% (11/11). In conclusion, lymphocytes isolated from a single endoscopic biopsy specimen using our simplified and quick procedure are suitable for flow cytometry. Considering that flow cytometry has an important advantage of providing the results on the examination day itself, the results of this study suggest that flow cytometric analysis using our single-step lymphocyte isolation technique can be potentially used to diagnose lymphoma in the gastrointestinal mucosa.

en-abstract=
kn-abstract=A 55-year-old Japanese woman, who had been diagnosed with ulcerative colitis at 18 years of age, underwent screening endoscopy examinations. Esophagogastroduodenoscopy revealed an extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma) of the stomach. Colonoscopy showed a slightly elevated reddish lesion with dilated microvessels but no erosions or ulcers. Although MALT lymphoma in the cecum was endoscopically suspected, flow cytometry and pathological analyses led to the diagnosis of appendiceal orifice inflammation in ulcerative colitis. This case highlights the diversity of the endoscopic appearance of appendiceal orifice inflammation in ulcerative colitis.

kn-title=The efficacy of pancreatic juice cytology with liquid-based cytology for evaluating malignancy in patients with intraductal papillary mucinous neoplasm
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Background</br>
Pancreatic juice cytology (PJC) is a tool for diagnosing malignant intraductal papillary mucinous neoplasm (IPMN); however, the accuracy is insufficient using the conventional method. Liquid-based cytology (LBC) improves the cell recovery rate, and almost all cells can be evaluated. We evaluated the efficacy of PJC with LBC for malignant IPMN.</br>
Methods</br>
We retrospectively analyzed 90 patients with suspected malignant IPMN who underwent PJC before pancreatectomy. PJC with smear and LBC methods was conducted in 52 patients (between June 2003 to December 2011) and 38 patients (between January 2012 to December 2018). Based on the imaging studies, all of the patients were classified according to the international consensus guidelines for IPMN revised in 2017.</br>
Results</br>
Of the 90 patients, 43 (48%) had malignant IPMN (high-grade dysplasia or invasive carcinoma), and the remaining patients had non-malignant IPMN (intermediate- or low-grade dysplasia). LBC increased the accuracy of PJC for the diagnosis of malignant IPMN (smear method: 56% [29/52] vs. LBC method: 76% [29/38]; P?=?0.044). In a multivariate analysis, LBC was a significant factor influencing the accurate diagnosis of PJC (odds ratio: 3.52; P?=?0.021). Furthermore, LBC increased the accuracy of PJC for malignant IPMN in patients with worrisome features (smear method: 66% [19/29] vs. LBC method: 93% [14/15]; P?=?0.043).</br>
Conclusions</br>
LBC increases the accuracy of PJC for diagnosing malignant IPMN compared with the conventional smear method.

kn-title=Pathologically Proven Intraocular Infiltration With Adult T-Cell Leukemia/Lymphoma: Two New Cases With Either Vitreous Opacity or Aqueous Hypopyon and Literature Review of 16 Cases
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=This study reported 2 new patients and 16 historical cases with pathologically proven intraocular infiltration with adult T-cell leukemia and lymphoma (ATLL) to know the timing of intraocular infiltration in the disease course. The first case was a 67-year-old woman who developed bilateral vitreous opacity about half a year after the onset of acute type of ATLL that had been unresponsive to chemotherapy. She underwent vitrectomy combined with cataract surgery in both eyes. She had bilateral optic disc atrophy and localized retinal white infiltrates in both eyes. Cytological examination of vitreous aspirates demonstrated medium-sized cells with aberrant flower-like convoluted nuclei, positive for CD3, and thus indicative of T-cells. The second case was a 38-year-old man who was diagnosed acute type of ATLL at the presentation of acute kidney injury. About half a year after initial chemotherapy and allogeneic hematopoietic stem cell transplantation, he developed aqueous hypopyon in the right eye, concurrent with cutaneous and central nervous system relapse. Aqueous tap disclosed class V abnormal cells. The aqueous “pseudohypopyon” resolved in response to another round of chemotherapy with mogamulizumab. In review of 18 patients, intraocular infiltration with ATLL was diagnosed by vitrectomy in 9, aqueous tap in 3, chorioretinal biopsy in 3, and autopsy in 3. The intraocular infiltration developed concurrently with systemic diagnosis of ATLL in 5 patients, but developed later after chemotherapy in 13. In conclusion, intraocular infiltration with ATLL appears rare, and pathological diagnosis by vitrectomy and aqueous tap would help determine therapeutic plan in relapse after chemotherapy.

kn-title=Eosinophilic Gastritis in a Patient Previously Treated with Dupilumab
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=A 77-year-old Japanese man with bronchial asthma was treated with dupilumab. Dupilumab treatment was discontinued at the patient's request after two injections separated by a 2-week interval. The blood eosinophil count was elevated, and an esophagogastroduodenoscopy performed 3 months after dupilumab treatment revealed gastric ulcers; subsequently, eosinophilic gastritis was diagnosed from biopsy examinations. The gastric lesions were resolved by steroid administration. This case report underscores that eosinophil-associated gastrointestinal diseases should be considered in the differential diagnosis of gastric lesions occurring in patients who were treated with dupilumab.

kn-title=Influences of preoperative metformin on immunological factors in early breast cancer
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Purpose</br>
Metformin has been suggested to possibly reduce cancer risk. However, the mechanism underlying the positive effects of metformin on cancer treatment remains unclear. We conducted a prospective study to evaluate the effects of preoperative metformin in patients with early breast cancer.</br>
Method</br>
We evaluated the effects on immunological factors (TILs, CD4?+?, CD8?+?, PD-L1, IFNγ and IL-2) by comparing core needle biopsies (CNB) obtained before metformin treatment with surgical specimens. Seventeen patients were enrolled in this prospective study from January to December 2016. We also analyzed 59 patients undergoing surgery during the same period to reveal the correlation of immune factors between CNB and surgical specimen.</br>
Result</br>
There was a moderate correlation between CNB and surgical specimens on TILs and CD8?+?lymphocyte. (TILs Rs?=?0.63, CD4?+?Rs?=?0.224, CD8?+?Rs?=?0.42) In the metformin group, TILs increases were confirmed in five (29%) patients, while a decrease was confirmed in two (12%). The expressions of CD4?+ and CD8?+?by TILs were increased in 41% and 18% of surgical specimens, respectively. However, TILs number (p?=?0.0554), CD4+ (p?=?0.0613) and CD8?+?(p?=?0.0646) expressions did not significantly increased. Furthermore, IFNγ expression appeared to be increased in response to metformin (p?=?0.08).</br>
Conclusion</br>
Preoperative metformin tends to increase TILs, as well as the numbers of CD4 and CD8 positive lymphocytes, and IFNγ levels. Metformin might improve immune function and have a possibility of chemo-sensitivity and thereby increase the effectiveness of immunotherapy, based on the results of this preliminary study.

kn-title=Diagnostic Role of 18F-Fluorodeoxyglucose Positron Emission Tomography in Gastric Mesenchymal Tumors
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=There have been no comparative studies investigating the results of 18F-fluorodeoxyglucose (FDG)-positron emission tomography (PET) in patients with gastric mesenchymal tumors, including leiomyomas, leiomyosarcomas, schwannomas, and gastrointestinal stromal tumors (GISTs). We retrospectively reviewed the data of 142 patients with pathologically diagnosed gastric mesenchymal tumors treated at 11 institutions. We analyzed the correlation between the maximum standardized uptake value (SUVmax) evaluated using fluorodeoxyglucose-positron emission tomography (FDG-PET) and the tumor size. The correlation between the SUVmax and mitotic index was also investigated in GISTs. The SUVmax (mean +/- standard deviation) was 0.5 +/- 0.6 in very low-risk GISTs (n = 42), 2.1 +/- 0.7 in low-risk GISTs (n = 26), 4.9 +/- 0.8 in intermediate-risk GISTs (n = 22), 12.3 +/- 0.8 in high-risk GISTs (n = 20), 1.0 +/- 1.0 in leiomyomas (n = 15), 6.9 +/- 1.2 in schwannomas (n = 10), and 3.5 in a leiomyosarcoma (n = 1). The SUVmax of GISTs with an undetermined risk classification was 4.2 +/- 1.3 (n = 8). Linear associations were observed between the SUVmax and tumor size in GISTs, leiomyomas, and schwannomas. The SUVmax of GISTs with a high mitotic index was significantly higher than that of GISTs with a low mitotic index (9.6 +/- 7.6 vs. 2.4 +/- 4.2). In conclusion, we observed positive correlations between the SUVmax and tumor size in GISTs, leiomyomas, and schwannomas. The SUVmax also positively correlated with the mitotic index and risk grade in GISTs. Schwannomas showed a higher FDG uptake than GISTs and leiomyomas.

kn-abstract=A 44-year-old Japanese woman with systemic lupus erythematosus (SLE) presented to our hospital with abdominal pain. Radiological and endoscopic examinations led to the diagnosis of diffuse large B-cell lymphoma of the jejunum, which was subsequently resected. Patients with SLE reportedly have an increased risk of non-Hodgkin lymphoma, as demonstrated by our patient. Hence, lymphoma should be considered in the differential diagnosis of neoplastic lesions emerging in SLE patients. In addition, flow cytometry using endoscopically biopsied fragments is useful for the immediate diagnosis of lymphoma, leading to timely and accurate preoperative staging.

en-abstract=
kn-abstract= The aim of this study was to explore enhancement patterns of different types of primary lung cancers on 2-phase dynamic computed tomography (CT). This study included 217 primary lung cancer patients (141 adenocarcinomas [ADs], 48 squamous cell carcinomas [SCCs], 20 small cell lung carcinomas [SCLCs], and 8 others) who were examined using a 2-phase dynamic scan. Regions of interest were identified and mean enhancement values were calculated. After excluding the 20 SCLCs because these lesions had different clinical stages from the other cancer types, the mean attenuation values and subtractions between phases were compared between types of non-small cell lung carcinomas (NSCLCs) using the Kruskal?Wallis test. Late phase attenuation and attenuation of the late minus unenhanced phase (LMU) of SCCs were significantly higher than those of ADs (p<0.05). To differentiate SCC and AD in the late phase, a threshold of 80.21 Hounsfield units (HU) gave 52.9% accuracy. In LMU, a threshold of 52.16 HU gave 59.3% accuracy. Dynamic lung CT has the potential to aid in differentiating among NSCLC types.

kn-title=The Diagnostic Capacity of Pre-treatment 18F-FDG PET/CT for Predicting the Extranodular Spread of Lymph Node Metastases in Patients with Oral Squamous Cell Carcinoma
en-subtitle=

en-abstract=
kn-abstract= The aim of this study was to evaluate the ability of pretreatment 90-min 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) to predict the extranodular spread of lymph node metastases in oral squamous cell carcinoma. We retrospectively reviewed the cases of 56 patients who underwent pretreatment 18F-FDG PET/CT and surgery with neck dissection. Maximum standardized uptake value, metabolic tumor volume, and total lesion glycolysis were measured for the 56 primary sites and maximum standardized uptake value was measured for 115 lymph node levels. Extranodular spread was present at 9 lymph node levels in 7 patients. Significant differences were found in metabolic tumor volume and total lesion glycolysis of the primary site, and in lymph node maximum standardized uptake value, between patients with and without extranodular spread (p<0.05). Combining primary site total lesion glycolysis and lymph node maximum standardized uptake volume at their respective optimal cutoffs, the sensitivity, specificity, and accuracy for predicting extranodular spread were 89%, 92%, and 92%, respectively. Pretreatment 18F-FDG PET/CT is useful for predicting extranodular spread in patients with oral squamous cell carcinoma. The combined use of primary site total lesion glycolysis and lymph node maximum standardized uptake value showed greater predictive value than either predictor singly.

kn-abstract=Primary intraocular lymphomas frequently develop into central nervous system lymphomas and vice versa. This study reviewed 22 consecutive patients with primary intraocular lymphoma diagnosed by immunostaining of vitrectomy cell blocks, and examined whether they developed central nervous system lymphoma. Seventeen patients developed central nervous system lymphoma: 3 patients developed intraocular and central nervous system lymphoma simultaneously, 9 patients developed central nervous system lymphoma 1 month to 5 years (median, 3 months) after intraocular lymphoma, and 5 patients developed central nervous system lymphoma preceding the diagnosis of intraocular lymphoma by 3 months to 9 years and 8 months (median, 1.5 years). In contrast, 5 patients did not develop central nervous system lymphoma: 2 patients did not develop local recurrence or central nervous system lymphoma in the follow-up period of 5 years and 11 years, respectively, after vitrectomy alone without additional local or systemic treatment. The remaining 3 patients with intraocular lymphoma had insufficient follow-up periods to determine the prognosis. The results of CD5 immunostaining of vitrectomy specimens were found in pathology reports of 8 patients: 3 patients with CD5-positive large cells and 4 patients with CD5-negative large cells developed central nervous system lymphoma. In summary, only a small number of patients did not develop central nervous system lymphoma based on long-term follow-up after vitrectomy alone. CD5 was not a marker of central nervous system involvement in this study population.

kn-title=PD-L1 expression combined with microsatellite instability/CD8+tumor infiltrating lymphocytes as a useful prognostic biomarker in gastric cancer
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=While the importance of programmed death-ligand 1 (PD-L1), mutation burden caused by microsatellite instability (MSI), and CD8+ tumor infiltrating lymphocytes (TILs) has become evident, the significance of PD-L1 expression on prognosis still remains controversial. We evaluated the usefulness of combined markers of PD-L1 and MSI or CD8+ TILs as a prognostic biomarker in gastric cancer. A total of 283 patients with gastric cancer were reviewed retrospectively. PD-L1 expression on >5% tumor cells was defined as PD-L1-positive. PD-L1-positive rate was 15.5% (44/283). PD-L1 positivity was significantly correlated with invasive and advanced cancer and also significantly correlated with MSI, whereas no significance was observed with CD8+ TILs. Kaplan-Meier analysis showed that PD-L1 positivity significantly correlated with a poor prognosis (p = 0.0025). Multivariate analysis revealed that PD-L1 positivity was an independent poor prognostic factor (hazard ratio [HR]: 1.97, p = 0.0106) along with diffuse histological type and lymph node metastases. Combinations of PD-L1 and MSI (HR: 2.18) or CD8+ TILs (HR: 2.57) were stronger predictive factors for prognosis than PD-L1 alone. In conclusion, combined markers of PD-L1 and MSI or CD8+ TILs may be more useful prognostic biomarkers in gastric cancer, and better clarify the immune status of gastric cancer

kn-title=Lacrimal Sac Malignant Melanoma in 15 Japanese Patients: Case Report and Literature Review
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Background. Primary malignant melanoma of the lacrimal sac is rare. A patient with lacrimal sac melanoma was presented, and 14 Japanese patients with lacrimal sac melanoma in the literature were reviewed. Case Presentation. A 78-year-old Japanese man was presented with painless swelling of the lacrimal sac on the left side. Dacryocystectomy revealed diffuse infiltration with large epithelioid cells, sometimes with pigments, which were positive for cocktail mix of antibodies to tyrosinase, melan A (MART-1), and HMB45, leading to pathological diagnosis of melanoma. One month later, positron emission tomography (PET) revealed 2 high-uptake sites (SUVmax = 10.29 and 15.38) at the levels of medial canthus and nasolacrimal duct, but no abnormal uptake in the other site of the body. The lesion had the BRAF V600E mutation. He began to take daily oral dabrafenib (BRAF inhibitor) and trametinib (MEK inhibitor), leading to no abnormal uptake on PET in half a year. He had stable disease in good physical status with small and weak uptake sites of lymph nodes on PET 1 year later. Results. In the review of 15 Japanese patients, including this patient, local recurrence was noted in 4 patients, regional lymph node metastasis only in 3, distant metastasis in 6, and no metastasis in 6. Five patients died within 2 years and the others were alive in short follow-up periods. Conclusions. Chemotherapy was the standard for local recurrence or metastasis. Emerging molecular target drugs, as shown in the present patient, would change the strategy for management of lacrimal sac melanoma.

kn-title=Two cases of gastric mucosa-associated lymphoid tissue (MALT) lymphoma masquerading as follicular gastritis
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract= In this report, we describe two cases of extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma) of the stomach, which presented with multiple small, whitish nodules in the gastric body. The endoscopic appearance was similar to that of lymphoid follicular hyperplasia found in follicular gastritis or nodular gastritis. Both patients were positive for Helicobacter pylori, and the eradication treatment resulted in complete remission of the lymphoma. However, recurrence was noted in one patient. These cases indicate that, although infrequent, gastric MALT lymphoma can show a nodular appearance resembling that of follicular gastritis.

kn-title=Long-Term Outcome in Patients with a Solitary Peutz-Jeghers Polyp

kn-abstract=BACKGROUND:<br/>
Clinical characteristics and prognosis of patients with a solitary Peutz-Jeghers polyp (PJP) have not been fully investigated.<br/>
METHODS:<br/>
Solitary PJP was diagnosed when a single hamartomatous lesion was identified in the gastrointestinal tract of patients without mucocutaneous pigmentation or a family history of Peutz-Jeghers syndrome. We retrospectively reviewed 51 patients (32 men and 19 women) with a solitary PJP and analyzed the sex, age at diagnosis, endoscopic features, and outcomes in this patient group. The STK11/LKB1 germline mutation was not investigated in any of the patients.<br/>
RESULTS:<br/>
The mean age of the 51 patients was 66.1 years. The polyp was found in the duodenum (N = 10), jejunum (N = 2), cecum (N = 2), transverse colon (N = 5), sigmoid colon (N = 21), or rectum (N = 11). Most of the polyps presented as a pedunculated lesion (N = 40), followed by semipedunculated (N = 9) and sessile (N = 2) morphologies. The mean size of a solitary PJP was 15.6?mm (range: 5 to 33?mm). During a mean endoscopic follow-up period of 4.5 years (range: 0.1 to 16.1 years), no recurrence was identified. Eighteen of the enrolled patients had a history of cancer or concomitant cancer. Five patients died due to non-gastrointestinal-related causes. No additional cancer or death directly related to solitary PJP was observed.<br/>
CONCLUSIONS:<br/>
Solitary PJPs did not recur in this study. Although examination of the entire gastrointestinal tract using esophagogastroduodenoscopy, enteroscopy, and colonoscopy is desirable to exclude Peutz-Jeghers syndrome, follow-up endoscopy after endoscopic polyp resection may be unnecessary, once the diagnosis of a solitary PJP is made.

kn-abstract= A 60-year-old Caucasian male was diagnosed with lung adenocarcinoma and multiple metastases to the bone, spleen, and brain. He underwent radiotherapy for the brain and lumbar spine metastases, plus chemotherapy (cisplatin and pemetrexed). The chemotherapy was discontinued due to vomiting and hyponatremia, and nivolumab was then administered. Eight months later, 18F-fluorodeoxyglucose positron emission tomography showed tracer uptake in the colon. Colonoscopy revealed a reddish multinodular polyp in the sigmoid colon. The polyp showed irregular microvessels. No colonic mucosal surface structures were observed. Colonic metastasis of the lung carcinoma was highly suspected; the polyp was therefore surgically removed. The histological analysis revealed granulation tissue and suppurative inflammation without neoplastic changes. We diagnosed the lesion as a granulation polyp. Despite the difficulty in diagnosing these lesions due to their rarity and similarity to metastatic colon tumors, we suggest that recognizing the endoscopic features of the polyp surface may allow a preoperative diagnosis.

en-abstract=
kn-abstract=Intrapulmonary solitary fibrous tumors (SFTs) are extremely rare neoplasms. We report a case of an intrapulmonary SFT and describe the findings of computed tomography (CT) and F-18 fluorodeoxyglucose positron emission tomography. The case indicates that a benign intrapulmonary SFT can present as a ground-glass nodule in the early stages of disease and may appear as a well-defined, lobular, homogeneously enhanced mass with slow growth on chest CT images. To our knowledge, this is the first report describing the natural course of an intrapulmonary SFT over 16 years based on the findings of chest CT and F-18 fluorodeoxyglucose positron emission tomography/CT.

en-abstract=
kn-abstract= Chronic GVHD (cGVHD) is a main cause of late death and morbidity after allogeneic hematopoietic cell transplantation, but its pathogenesis remains unclear. We investigated the roles of Th subsets in cGVHD with the use of a well-defined mouse model of cGVHD. In this model, development of cGVHD was associated with up-regulated Th1, Th2, and Th17 responses. Th1 and Th2 responses were up-regulated early after BM transplantation, followed by a subsequent up-regulation of Th17 cells. Significantly greater numbers of Th17 cells were infiltrated in the lung and liver from allogeneic recipients than those from syngeneic recipients. We then evaluated the roles of Th1 and Th17 in cGVHD with the use of IFN-γ-deficient and IL-17-deficient mice as donors. Infusion of IFN-γ(-/-) or IL-17(-/-) T cells attenuated cGVHD in the skin and salivary glands. Am80, a potent synthetic retinoid, regulated both Th1 and Th17 responses as well as TGF-β expression in the skin, resulting in an attenuation of cutaneous cGVHD. These results suggest that Th1 and Th17 contribute to the development of cGVHD and that targeting Th1 and Th17 may therefore represent a promising therapeutic strategy for preventing and treating cGVHD.

en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=　D cyclins positively regulate the cell cycle and mediate the pathogenesis of some lymphomas. Cyclin D1 overexpression is the hallmark of mantle cell lymphoma, whereas cyclins D2 and D3 are reportedly not as specific to certain lymphomas as cyclin D1. In this study, cyclin D2 was found to be overexpressed in 98% of de novo CD5-positive diffuse large B-cell lymphomas (DLBCLs) (50/51) and in 28% of CD5-negative DLBCLs (14/51). A statistically significant difference was observed between these two groups (p<0.0001). In contrast, no statistical difference was found in the cyclin D3 expression between CD5-positive (18/51) and CD5-negative (24/51) DLBCLs (p=0.23). Based on these findings, cyclin D2 is therefore considered to be closely associated with de novo CD5-positive DLBCLs. This insight may be useful for overcoming the inferior survival of this aggressive lymphoma.

kn-abstract=We retrospectively analyzed the cases of 14 patients (9 women, 5 men, mean age: 51.6 years) with cytomegalovirus (CMV) involvement in the esophagus, stomach, and/or duodenum diagnosed at a single center, to determine their endoscopic features and clinical backgrounds. Thirteen patients (92.9%) had hematologic disease; the other had rheumatoid arthritis. Of the former, 12 patients underwent allogeneic hematopoietic stem cell transplantation, and 9 of these patients had graft-versus-host disease (GVHD) before undergoing esophagogastroduodenoscopy (EGD). All 14 patients had been taking one or more immunosuppressive agents including cyclosporine (n=10), corticosteroids (n=9), mycophenolic acid (n=6), tacrolimus (n=3), and methotrexate (n=1). Tests for CMV antigenemia were positive in 11 patients (78.6%). EGD examinations revealed esophageal (n=3), gastric (n=9), and duodenal involvement (n=6). Macroscopically, esophageal lesions by CMV infection presented as redness (n=1), erosions (n=1), and ulcers (n=1). Gastric lesions manifested as redness (n=7), erosions (n=3), exfoliated mucosa (n=2), and verrucous erosions (n=1). Mucosal appearances in the duodenum varied: redness (n=2), ulcers (n=2), multiple erosions (n=2), single erosion (n=1), edema (n=1). CMV was detected even in the intact duodenal mucosa (n=1). In conclusion, physicians must recall the relevance of CMV infection when any mucosal alterations exist in the upper gastrointestinal tract of immunosuppressed patients.

kn-title=Lanthanum Deposition in the Stomach: Usefulness of Scanning Electron Microscopy for Its Detection
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=After having been treated with lanthanum carbonate administration for 4 years for hyperphosphatemia, a 75-year-old Japanese woman undergoing hemodialysis was diagnosed with lanthanum phosphate deposition in the stomach. The deposition, seen as white microgranules, was observed using esophagogastroduodenoscopy with magnifying observation. To the best of our knowledge, these are the minutest endoscopy images of lanthanum phosphate deposition in the gastric mucosa. Scanning electron microscopy (SEM) observation enabled easier identification of the deposited material, which was visible as bright areas. The present case suggests the usefulness of SEM observation in the detection of lanthanum phosphate deposition in the gastrointestinal tract.

kn-title=Acute Bowel Injury due to Cryoablation for Renal Cell Carcinoma: Correlated Radiologic and Pathologic Findings
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=An 87-year-old Japanese man underwent percutaneous cryoablation (PCA) therapy for his renal cell tumor. We displaced the colon from the tumor using hydrodissection. Computed tomography (CT) immediately after PCA was indicative of iceball extension to the colon wall, and a discontinuous enhancement of the colon wall was observed. We therefore performed an emergency surgery. On laparotomy, we observed a dark-purple area on the affected area of the colon, and the resected specimen showed focal, deep ulceration on the mucosal surface. Photomicrography revealed mucosal necrosis, submucosal hemorrhage, and necrotic foci in the muscularis propria, corresponding to the discontinuous colon wall enhancement on CT and the deep ulceration and dark-purple area on laparotomy. He recovered from surgery and was discharged without any complications.

kn-title=Two Relapsed Stage III Childhood Anaplastic Large Cell Lymphoma Patients with NPM-ALK Fusion in Bone Marrow from Initial Diagnosis
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Childhood anaplastic large cell lymphoma (ALCL) accounts for approx. 10?30 of cases of non-Hodgkin lymphoma, and the ALCL99 study reported 60?75 disease-free survival; however, a relatively high relapse rate was observed (25?30 ). We report 2 patients with Stage III ALCL who relapsed 6?18 months after the end of ALCL99 chemotherapy. A retrospective molecular analysis identified the nucleophosmin (NPM)-anaplastic lymphoma kinase (ALK) fusion gene in the first diagnostic bone marrow samples taken from both patients. However, antibodies against the ALK protein appeared to be relatively low in the serum of both patients (×100 and ×750). An increase in chemotherapy intensity may be beneficial if Stage III ALCL patients are shown to be NPM-ALK chimera-positive in the first diagnostic bone marrow sample.

kn-abstract=　Esophageal neuroendocrine carcinoma （ECC） is rare and has a poor prognosis when presenting with vascular invasion and distant metastasis from an early stage. Multidisciplinary therapy with surgery, chemotherapy, and radiation therapy may prolong survival in patients with advanced ECC, but there is as yet no standard therapy for advanced ECC. We treated two patients who have achieved long-term survival （＞ 4 years） who underwent multidisciplinary therapy, including chemotherapy, for ECC. Our experience with these two cases suggests that multidisciplinary therapy, including chemotherapy, may be effective for treating ECC at an advanced stage.

kn-abstract= A 43-year-old Japanese woman was diagnosed with ectopic sebaceous glands in the esophagus by esophagogastroduodenoscopy and biopsy. At the age of 46, typical ectopic sebaceous glands were recognized in the upper esophagus, whereas yellowish white granules were faintly observed in the lower esophagus. Esophagogastroduodenoscopy examinations were repeated when she was 47 and again at 50 years old, and the lesions in the lower esophagus had become more evident over the ensuing 3 years. Esophageal ectopic sebaceous glands are relatively infrequent, and there have been few case reports describing the progression of the endoscopic features. We also report the clinical and endoscopic features of the five similar cases with pathologically proven ectopic sebaceous glands in the esophagus.

en-subtitle=

en-abstract=
kn-abstract=A 61-year-old Japanese man with IgG4-related autoimmune pancreatitis was referred to our hospital because of perspiration during food intake. Abdominal computed tomography (CT) with contrast media revealed multiple mesenteric lymphadenopathies. An open surgical abdominal biopsy and subsequent histopathological analysis revealed abnormally large lymphoid cells that were negative for CD3, CD5, and c-myc and positive for CD20 and bcl-2, leading to a diagnosis of diffuse large B-cell lymphoma. Here, we discuss the risk of malignancies, particularly malignant lymphoma in patients with IgG4-related disease. The importance of pathological analysis to reach the appropriate diagnosis in such cases should be emphasized.

en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=A 60-year-old woman with rheumatoid arthritis treated with methotrexate for a decade complained of slight epigastric discomfort. A positive cytomegalovirus (CMV) antigenemia test indicated the probability of CMV-related gastrointestinal infection, for which esophagogastroduodenoscopy was performed. Endoscopic findings showed a non-specific duodenal mucosal lesion;however, pathological investigation revealed evidence of CMV duodenitis. There is scarce information on the clinical and pathological features of CMV-related duodenitis, likely due to its low prevalence. CMV infection in the upper gastrointestinal tract should be considered as a differential diagnosis in high-risk individuals, particularly those with symptoms relating to the digestive system. Biopsy examinations are preferable for the definitive diagnosis of CMV gastrointestinal infection, even without specific endoscopic features.

kn-title=Magnified Endoscopic Features of Duodenal Follicular Lymphoma and Other Whitish Lesions
en-subtitle=

en-abstract=
kn-abstract=The sensitivity and specificity of magnified endoscopic features for differentiating follicular lymphoma from other diseases with duodenal whitish lesions have never been investigated. Here we compared the magnified endoscopic features of duodenal follicular lymphoma with those of other whitish lesions. We retrospectively reviewed the cases of patients with follicular lymphoma (n＝9), lymphangiectasia (n＝7), adenoma (n＝10), duodenitis (n＝4), erosion (n＝1), lymphangioma (n＝1), and hyperplastic polyp (n＝1). The magnified features of the nine follicular lymphomas included enlarged villi (n＝8), dilated microvessels (n＝5), and opaque white spots of various sizes (n＝9). The lymphangiectasias showed enlarged villi, dilated microvessels, and white spots, but the sizes of the white spots were relatively homogeneous and their margin was clear. Observation of the adenoma and duodenitis revealed only whitish villi. Although the lymphangioma was indistinguishable from the follicular lymphomas by magnified features, it was easily diagnosed based on the macroscopic morphology. In conclusion, magnified endoscopic features, in combination with macroscopic features, are useful for differentiating follicular lymphomas from other duodenal diseases presenting whitish lesions.

kn-title=Prompt Resolution of Hypoglycemia by Hepatic Transarterial Embolization for Malignant Insulinoma with Multiple Liver Metastases
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=A 45-year-old female who presented with loss of consciousness and a cold sweat was found to have a pancreatic tumor and multiple liver metastases. Laboratory studies showed marked hypoglycemia and inappropriately elevated serum insulin, C-peptide, and serum tumor markers. Fine needle aspiration revealed Grade 3 small-cell type primary pancreatic neuroendocrine carcinoma. Consequently, the diagnosis of malignant insulinoma was made. Transarterial embolization (TAE) for hepatic metastases resulted in the reduction of tumor volume and prompt resolution of hypoglycemic attacks, whereas diazoxide and systemic chemotherapy had been ineffective for controlling blood glucose levels, and octreotide was unavailable due to the allergic effect. This case report highlights the potential usefulness of TAE for malignant insulinomas in the management of hypoglycemia.

en-subtitle=

en-abstract=
kn-abstract=Chronic graft-versus-host disease (GVHD) remains a major late complication of allogeneic bone marrow transplantation (BMT). In a previous study, impaired thymic negative selection of the recipients permitted the emergence of pathogenic T cells that cause chronic GVHD using MHC class II-deficient (H2-Ab1 KO) B6 into OH model and CD4(+) T cells isolated from chronic GVHD mice caused chronic GVHD when administered into the secondary recipients. In this study, we evaluated the kinetics of regulatory T cell (Treg) reconstitution in wild type B6 into C3H model. After myeloablative conditioning, host Tregs disappeared rapidly, followed by expansion of Tregs derived from the donor splenic T cell inoculum. However, the donor splenic T cell derived Treg pool contracted gradually and was almost completely replaced by newly generated donor bone marrow (BM)-derived Tregs in the late post-transplantation period. Next, we compared the effects of cyclosporine (CSA) and mammalian target of rapamycin (mTOR) inhibitors on Treg reconstitution. Administration of CSA significantly impaired Treg reconstitution in the spleen and thymus. In contrast, BM-derived Treg reconstitution was not impaired in mTOR inhibitor-treated mice. Histopathological examination indicated that mice treated with GSA, but not mTOR inhibitors, showed pathogenic features of chronic GVHD on day 120. Mice treated with CSA until day 60, but not mTOR inhibitors, developed severe chronic GVHD followed by adoptive transfer of the pathogenic CD4(+) T cells isolated from H2-Ab1 KO into C3H model. These findings indicated that long-term use of CSA impairs reconstitution of BM-derived Tregs and increases the liability to chronic GVHD. The choice of immunosuppression, such as calcineurin inhibitor-free GVHD prophylaxis with mTOR inhibitor, may have important implications for the control of chronic GVHD after BMT.

kn-title=Primary Tracheal Malignant Lymphoma Detected during a Regular Checkup in an Asbestos Dust-Exposed Smoker
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Primary tracheal malignant lymphoma is a rare disease;only 30 cases have been reported to date. A 73-year-old Japanese man with a history of asbestos exposure was undergoing biannual chest computed tomography (CT) twice a year as a routine procedure for those previously exposed to asbestos. He had been smoking since the age of 32. In September 2010, chest CT during this regular checkup revealed a polypoid lesion in his trachea and pleural plaques, which were suspected to be caused by asbestos. Bronchoscopy performed in October revealed a polypoid lesion with granules and nodules in the trachea. A diagnosis of non-Hodgkin lymphoma (NHL) and extranodal marginal-zone B-cell lymphoma of mucosa-associated lymphoid tissue (MALT) was confirmed by histological analysis of the biopsy specimens. To our knowledge, this is the first case of primary tracheal lymphoma associated with a history of asbestos exposure. Several reports have documented no correlation between asbestos and malignant lymphoma. In addition, the correlation between smoking and NHL is weak. Although we cannot exclude the possibility of a simple coincidence of asbestos, smoking, and tracheal lymphoma, this case suggests that asbestos and smoking might have multiplicative effects in the development or progression of tracheal lymphoma.

kn-title=CD14 upregulation as a distinct feature of non-alcoholic fatty liver disease after pancreatoduodenectomy
en-subtitle=

en-abstract=
kn-abstract=AIM: To investigate the pathogenesis of non-alcoholic fatty liver disease (NAFLD) after pancreatoduodenectomy (PD).

METHODS: A cohort of 82 patients who underwent PD at Okayama University Hospital between 2003 and 2009 was enrolled and the clinicopathological features were compared between patients with and without NAFLD after PD. Computed tomography (CT) images were evaluated every 6 mo after PD for follow-up. Hepatic steatosis was diagnosed on CT when hepatic attenuation values were 40 Hounsfield units. Liver biopsy was performed for 4 of 30 patients with NAFLD after PD who consented to undergo biopsies. To compare NAFLD after PD with NAFLD associated with metabolic syndrome, liver samples were obtained from 10 patients with NAFLD associated with metabolic syndrome [fatty liver, n = 5; non-alcoholic steatohepatitis (NASH), n = 5] by percutaneous ultrasonography-guided liver biopsy. Double-fluorescence immunohistochemistry was applied to examine CD14 expression as a marker of lipopolysaccharide (LPS)-sensitized macrophage cells (Kupffer cells) in liver biopsy specimens.

RESULTS: The incidence of postoperative NAFLD was 36.6% (30/82). Univariate analysis identified cancer of the pancreatic head, sex, diameter of the main pancreatic duct, and dissection of the nerve plexus as factors associated with the development of NAFLD after PD. Those patients who developed NAFLD after PD demonstrated significantly decreased levels of serum albumin, total protein, cholesterol and triglycerides compared to patients without NAFLD after PD, but no glucose intolerance or insulin resistance. Liver biopsy was performed in four patients with NAFLD after PD. All four patients showed moderate-to-severe steatosis and NASH was diagnosed in two. Numbers of cells positive for CD68 (a marker of Kupffer cells) and CD14 (a marker of LPS-sensitized Kupffer cells) were counted in all biopsy specimens. The number of CD68+ cells in specimens of NAFLD after PD was significantly increased from that in specimens of NAFLD associated with metabolic syndrome specimens, which indicated the presence of significantly more Kupffer cells in NAFLD after PD than in NAFLD associated with metabolic syndrome. Similarly, more CD14+ cells, namely, LPS-sensitized Kupffer cells, were observed in NAFLD after PD than in NAFLD associated with metabolic syndrome. Regarding NASH, more CD68+ cells and CD14+ cells were observed in NASH after PD specimens than in NASH associated with metabolic syndrome. This showed that more Kupffer cells and more LPS-sensitized Kupffer cells were present in NASH after PD than in NASH associated with metabolic syndrome. These observations suggest that after PD, Kupffer cells and LPS-sensitized Kupffer cells were significantly upregulated, not only in NASH, but also in simple fatty liver.

CONCLUSION: NAFLD after PD is characterized by both malnutrition and the up-regulation of CD14 on Kupffer cells. Gut-derived endotoxin appears central to the development of NAFLD after PD.

kn-abstract=Background  
Recently, evidence in support of the cancer stem cell (CSC) hypothesis has been accumulating. On the other hand, it has been reported that the expression of aldehyde dehydrogenase 1 (ALDH1) in primary breast cancer is a powerful predictor of a poor clinical outcome, and that breast cancer stem cells express ALDH1. According to the CSC hypothesis, development of metastases requires the dissemination of CSC that may remain dormant and be reactivated to cause tumor recurrence. In this study, we investigated whether the detection of CSC in axillary lymph node metastases (ALNM) might be a significant prognostic factor in patients with breast cancer.
Methods  
From 1998 to 2006, 40 primary breast cancer patients with ALNM, the number of metastatic nodes varying in number from 1 to 3, underwent surgery at Okayama University; of these, 15 patients developed tumor recurrence. We retrospectively evaluated the common clinicopathological features and the expression of ER, HER2, ALDH1, and Ki67 in both the primary lesions and the ALNM, and analyzed the correlations between the expression of these biological markers and the disease-free survival (DFS).
Results  
Expression of ALDH1 in the ALNM was significantly associated with the DFS (P = 0.037).
Conclusion  
Evaluation of biomarker expression in ALNM could be useful for prognosis in breast cancer patients with 1?3 metastatic lymph nodes.
