This study aimed to analyze risk factors, including human papillomavirus (HPV) infection, as well as other factors associated with SNIP recurrence. Thirty-two patients who were diagnosed with SNIP and underwent surgery between 2010 and 2019 were enrolled: 24 men and 8 women, with a mean age of 59.2 years. The mean follow-up was 57.3 months. Demographics and information about history of smoking, diabetes mellitus (DM), hypertension, allergic rhinitis, alcohol consumption, tumor stage, surgical approach, and recurrence were reviewed retrospectively. Specimens were investigated using polymerase chain reaction to detect HPV DNA (high-risk subtypes: 16, 18, 31, 33, 35, 52b, and 58; low-risk subtypes: 6 and 11). Seven patients (21.9%) experienced recurrence. HPV DNA was detected in five (15.6%) patients (high-risk subtypes, n = 2; low-risk subtypes, n = 3). Patients with recurrence of SNIP had a higher proportion of young adults and displayed higher rates of HPV infection, DM, and advanced tumor stage than those without recurrence. HPV infection, young adulthood, DM, and advanced tumor stage could be associated with a high recurrence rate, which suggests that patients with these risk factors could require close follow-up after surgery. en-copyright= kn-copyright= en-aut-name=TsumuraMunechika en-aut-sei=Tsumura en-aut-mei=Munechika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MakiharaSeiichiro en-aut-sei=Makihara en-aut-mei=Seiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NishikoriAsami en-aut-sei=Nishikori en-aut-mei=Asami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=GionYuka en-aut-sei=Gion en-aut-mei=Yuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MoritoToshiaki en-aut-sei=Morito en-aut-mei=Toshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MiyamotoShotaro en-aut-sei=Miyamoto en-aut-mei=Shotaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NaitoTomoyuki en-aut-sei=Naito en-aut-mei=Tomoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=UraguchiKensuke en-aut-sei=Uraguchi en-aut-mei=Kensuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=OkaAiko en-aut-sei=Oka en-aut-mei=Aiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=TachibanaTomoyasu en-aut-sei=Tachibana en-aut-mei=Tomoyasu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=OritaYorihisa en-aut-sei=Orita en-aut-mei=Yorihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=KariyaShin en-aut-sei=Kariya en-aut-mei=Shin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=OkanoMitsuhiro en-aut-sei=Okano en-aut-mei=Mitsuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=AndoMizuo en-aut-sei=Ando en-aut-mei=Mizuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=SatoYasuharu en-aut-sei=Sato en-aut-mei=Yasuharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= affil-num=1 en-affil=Department of Otolaryngology Head and Neck Surgery, Kagawa Rosai Hospital kn-affil= affil-num=2 en-affil=Department of Otolaryngology Head and Neck Surgery, Dentistry and Pharmaceutical Sciences, Graduate School of Medicine, Okayama University kn-affil= affil-num=3 en-affil=Division of Pathophysiology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=4 en-affil=Division of Pathophysiology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=5 en-affil= kn-affil=Department of Pathology, Kagawa Rosai Hospital affil-num=6 en-affil=Department of Otolaryngology Head and Neck Surgery, Kagawa Rosai Hospital kn-affil= affil-num=7 en-affil=Department of Otorhinolaryngology, Kagawa Prefectural Central Hospital kn-affil= affil-num=8 en-affil=Department of Otolaryngology Head and Neck Surgery, Dentistry and Pharmaceutical Sciences, Graduate School of Medicine, Okayama University kn-affil= affil-num=9 en-affil=Department of Otorhinolaryngology, School of Medicine, International University of Health and Welfare kn-affil= affil-num=10 en-affil=Department of Otolaryngology, Japanese Red Cross Society Himeji Hospital kn-affil= affil-num=11 en-affil=Department of Otolaryngology Head and Neck Surgery, Graduate School of Medicine, Kumamoto University kn-affil= affil-num=12 en-affil=Department of Otolaryngology Head and Neck Surgery, Dentistry and Pharmaceutical Sciences, Graduate School of Medicine, Okayama University kn-affil= affil-num=13 en-affil= Department of Otorhinolaryngology, School of Medicine, International University of Health and Welfare kn-affil= affil-num=14 en-affil=Department of Otolaryngology Head and Neck Surgery, Dentistry and Pharmaceutical Sciences, Graduate School of Medicine, Okayama University kn-affil= affil-num=15 en-affil=Department of Pathology, Dentistry and Pharmaceutical Sciences, Graduate School of Medicine, Okayama University kn-affil= en-keyword=HPV infection kn-keyword=HPV infection en-keyword=sinonasal inverted papilloma kn-keyword=sinonasal inverted papilloma en-keyword=diabetes mellitus kn-keyword=diabetes mellitus en-keyword=young adult kn-keyword=young adult en-keyword=tumor stage kn-keyword=tumor stage END start-ver=1.4 cd-journal=joma no-vol=75 cd-vols= no-issue=1 article-no= start-page=31 end-page=37 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=202102 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Treatment Outcomes of Pulmonary Metastases from Head and Neck Squamous Cell Carcinoma en-subtitle= kn-subtitle= en-abstract= kn-abstract=Although the lung is the most common site of distant metastases from head and neck squamous cell carcinoma (HNSCC), the number of reports about the effects of pulmonary metastasectomy for the treatment of lung metastasis from HNSCC is limited. Metachronous pulmonary metastases were detected in 45 HNSCC patients at Kumamoto University Hospital from 1998 to 2018. Twenty-two patients underwent an operative resection (Ope group) and 23 underwent chemotherapy (Chemo group). The 3-year overall survival (OS) rate and median OS were evaluated. The effects of adjuvant chemotherapy after pulmonary metastasectomy and of new drugs (cetuximab and nivolumab), in the chemo group were also assessed. The 3-year OS rates and median OS were: Ope, 66.1% and 31.5 months; Chemo, 39.7% and 18 months, respectively. In the Ope group, addi-tional recurrences were significantly fewer in the patients who underwent adjuvant chemotherapy post-surgery versus the patients who underwent surgery alone (p = 0.013). In the Chemo group, the 3-year OS rate of the patients who received new drugs was significantly better than that of the patients who did not (p = 0.021). Adjuvant chemotherapy after pulmonary metastasectomy may be a preferable treatment option for preventing recurrences. Cetuximab and nivolumab have a potential to improve OS. en-copyright= kn-copyright= en-aut-name=MiyamaruSatoru en-aut-sei=Miyamaru en-aut-mei=Satoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MurakamiDaizo en-aut-sei=Murakami en-aut-mei=Daizo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NishimotoKohei en-aut-sei=Nishimoto en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SaitoHaruki en-aut-sei=Saito en-aut-mei=Haruki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MiyamotoYusuke en-aut-sei=Miyamoto en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HirotaKaoruko en-aut-sei=Hirota en-aut-mei=Kaoruko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=IseMomoko en-aut-sei=Ise en-aut-mei=Momoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OritaYorihisa en-aut-sei=Orita en-aut-mei=Yorihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Otolaryngology-Head and Neck Surgery, Graduate School of Medicine, Kumamoto University kn-affil= affil-num=2 en-affil=Department of Otolaryngology-Head and Neck Surgery, Graduate School of Medicine, Kumamoto University kn-affil= affil-num=3 en-affil=Department of Otolaryngology-Head and Neck Surgery, Graduate School of Medicine, Kumamoto University kn-affil= affil-num=4 en-affil=Department of Otolaryngology-Head and Neck Surgery, Graduate School of Medicine, Kumamoto University kn-affil= affil-num=5 en-affil=Department of Otolaryngology-Head and Neck Surgery, Graduate School of Medicine, Kumamoto University kn-affil= affil-num=6 en-affil=Department of Otolaryngology-Head and Neck Surgery, Graduate School of Medicine, Kumamoto University kn-affil= affil-num=7 en-affil=Department of Otolaryngology-Head and Neck Surgery, Graduate School of Medicine, Kumamoto University kn-affil= affil-num=8 en-affil=Department of Otolaryngology-Head and Neck Surgery, Graduate School of Medicine, Kumamoto University kn-affil= en-keyword=pulmonary metastasis kn-keyword=pulmonary metastasis en-keyword=head and neck squamous cell carcinoma kn-keyword=head and neck squamous cell carcinoma en-keyword=pulmonary metastasectomy kn-keyword=pulmonary metastasectomy en-keyword=adjuvant chemotherapy kn-keyword=adjuvant chemotherapy END start-ver=1.4 cd-journal=joma no-vol=21 cd-vols= no-issue=5 article-no= start-page=1843 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20200307 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Clinical Significance of Cytoplasmic IgE-Positive Mast Cells in Eosinophilic Chronic Rhinosinusitis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Cross-linking of antigen-specific IgE bound to the high-affinity IgE receptor (Fc epsilon RI) on the surface of mast cells with multivalent antigens results in the release of mediators and development of type 2 inflammation. Fc epsilon RI expression and IgE synthesis are, therefore, critical for type 2 inflammatory disease development. In an attempt to clarify the relationship between eosinophilic chronic rhinosinusitis (ECRS) and mast cell infiltration, we analyzed mast cell infiltration at lesion sites and determined its clinical significance. Mast cells are positive for c-kit, and IgE in uncinated tissues (UT) and nasal polyps (NP) were examined by immunohistochemistry. The number of positive cells and clinicopathological factors were analyzed. Patients with ECRS exhibited high levels of total IgE serum levels and elevated peripheral blood eosinophil ratios. As a result, the number of mast cells with membranes positive for c-kit and IgE increased significantly in lesions forming NP. Therefore, we classified IgE-positive mast cells into two groups: membrane IgE-positive cells and cytoplasmic IgE-positive cells. The amount of membrane IgE-positive mast cells was significantly increased in moderate ECRS. A positive correlation was found between the membrane IgE-positive cells and the radiological severity score, the ratio of eosinophils, and the total serum IgE level. The number of cytoplasmic IgE-positive mast cells was significantly increased in moderate and severe ECRS. A positive correlation was observed between the cytoplasmic IgE-positive cells and the radiological severity score, the ratio of eosinophils in the blood, and the total IgE level. These results suggest that the process of mast cell internalization of antigens via the IgE receptor is involved in ECRS pathogenesis. en-copyright= kn-copyright= en-aut-name=GionYuka en-aut-sei=Gion en-aut-mei=Yuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OkanoMitsuhiro en-aut-sei=Okano en-aut-mei=Mitsuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KoyamaTakahisa en-aut-sei=Koyama en-aut-mei=Takahisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OuraTokie en-aut-sei=Oura en-aut-mei=Tokie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NishikoriAsami en-aut-sei=Nishikori en-aut-mei=Asami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OritaYorihisa en-aut-sei=Orita en-aut-mei=Yorihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TachibanaTomoyasu en-aut-sei=Tachibana en-aut-mei=Tomoyasu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MarunakaHidenori en-aut-sei=Marunaka en-aut-mei=Hidenori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MakinoTakuma en-aut-sei=Makino en-aut-mei=Takuma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=NishizakiKazunori en-aut-sei=Nishizaki en-aut-mei=Kazunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=SatoYasuharu en-aut-sei=Sato en-aut-mei=Yasuharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Division of Pathophysiology, Okayama University Graduate School of Health Sciences kn-affil= affil-num=2 en-affil=Department of Otolaryngology of Head and Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Otolaryngology of Head and Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Division of Pathophysiology, Okayama University Graduate School of Health Sciences kn-affil= affil-num=5 en-affil=Division of Pathophysiology, Okayama University Graduate School of Health Sciences kn-affil= affil-num=6 en-affil=Department of Otolaryngology, Head and Neck Surgery, Kumamoto University Graduate School kn-affil= affil-num=7 en-affil=Department of Otolaryngology, Japanese Red Cross Society Himeji Hospital kn-affil= affil-num=8 en-affil=Department of Otolaryngology of Head and Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Otolaryngology of Head and Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Otolaryngology of Head and Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Division of Pathophysiology, Okayama University Graduate School of Health Sciences kn-affil= en-keyword=mast cell kn-keyword=mast cell en-keyword=eosinophilic chronic rhinosinusitis kn-keyword=eosinophilic chronic rhinosinusitis en-keyword=c-kit kn-keyword=c-kit en-keyword=IgE kn-keyword=IgE END start-ver=1.4 cd-journal=joma no-vol=9 cd-vols= no-issue= article-no= start-page=761 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=2019124 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Up-regulation of activation-induced cytidine deaminase and its strong expression in extra- germinal centres in IgG4-related disease en-subtitle= kn-subtitle= en-abstract= kn-abstract=Immunoglobulin (Ig) G4-related disease (IgG4-RD) is a systemic disorder involving benign mass formation due to fibrosis and intense lymphoplasmacytosis; the chronic inflammation associated with the disease might also contribute to oncogenesis. Activation-induced cytidine deaminase (AID), normally expressed in germinal centre activated B-cells, is an enzyme that edits DNA/RNA and induces somatic hypermutation and Ig class switching. AID expression is strictly controlled under physiological conditions; however, chronic inflammation and some infectious agents induce its up-regulation. AID is overexpressed in various cancers and may be important in chronic inflammation-associated oncogenesis. We examined AID expression in IgG4-related sialadenitis (n = 14), sialolithiasis (nonspecific inflammation, n = 13), and normal submandibular glands (n = 13) using immunohistochemistry and quantitative real-time polymerase chain reaction (qPCR). Immunohistochemistry revealed significantly more AID-expressing cells in IgG4-related sialadenitis than in sialolithiasis or normal submandibular gland samples (P = 0.02 and P < 0.01, respectively); qPCR yielded similar results. Thus, AID was significantly more up-regulated and had higher expression in extra-germinal centres in IgG4-RD than in non-specific inflammation or normal conditions. This report suggests that IgG4-RD has several specific causes of AID up-regulation in addition to inflammation. Furthermore, chronic inflammation-associated AID-mediated oncogenesis is possible in IgG4-RD. en-copyright= kn-copyright= en-aut-name=GionYuka en-aut-sei=Gion en-aut-mei=Yuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakeuchiMai en-aut-sei=Takeuchi en-aut-mei=Mai kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ShibataRei en-aut-sei=Shibata en-aut-mei=Rei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TakataKatsuyoshi en-aut-sei=Takata en-aut-mei=Katsuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=Miyata-TakataTomoko en-aut-sei=Miyata-Takata en-aut-mei=Tomoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OritaYorihisa en-aut-sei=Orita en-aut-mei=Yorihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TachibanaTomoyasu en-aut-sei=Tachibana en-aut-mei=Tomoyasu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YoshinoTadashi en-aut-sei=Yoshino en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=SatoYasuharu en-aut-sei=Sato en-aut-mei=Yasuharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Pathology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Pathology, Kurume University School of Medicine kn-affil= affil-num=3 en-affil=Department of Pathology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Pathology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Pathology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Otolaryngology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Otolaryngology, Himeji Red Cross Hospital kn-affil= affil-num=8 en-affil=Department of Pathology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Pathology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= END start-ver=1.4 cd-journal=joma no-vol=68 cd-vols= no-issue=2 article-no= start-page=216 end-page=224 dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=20190430 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Significance of IgG4-positive cells in severe eosinophilic chronic rhinosinusitis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: IgG4 production is regulated by type 2 (IL-4 and IL-13) and regulatory (IL-10) cytokines involved in the pathophysiology of chronic rhinosinusitis (CRS). We sought to determine the pathophysiological characteristics of IgG4-positive cells in sinonasal tissues in CRS, especially eosinophilic CRS (ECRS).
Methods: IgG4-positive cells in uncinate tissues (UT) and nasal polyps (NP) were examined by immunohistochemistry. Associations between the number of IgG4-positive cells and clinicopathological factors were analyzed. Receiver operating characteristics (ROC) analysis was performed to determine the cut-off value of IgG4-positive cells in tissue that can predict the post-operative course.
Results: IgG4 was mainly expressed in infiltrating plasma and plasmacytoid cells, and the number of IgG4-positive cells was significantly higher in NP, especially those from severe ECRS patients, than in UT. In CRS patients, the number of IgG4-positive cells significantly and positively correlated with blood and tissue eosinophilia, radiological severity, and serum level of total IgE. The number of infiltrating IgG4-positive cells was significantly higher in patients with a poor post-operative course (sustained sinus shadow 6 months after surgery) than in those with a good one. The number of IgG4-positive cells in NP could discriminate patients with a good or a poor post-operative course (area under the curve: 0.769). Also, 73.3% sensitivity and 82.5% specificity were achieved when the cut-off value was set at 17 cells/high-power field.
Conclusions: Our results suggest that the local expression of IgG4 on cells may be used as a biomarker that reflects the pathophysiology of CRS, including the post-operative course. en-copyright= kn-copyright= en-aut-name=KoyamaTakahisa en-aut-sei=Koyama en-aut-mei=Takahisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KariyaShin en-aut-sei=Kariya en-aut-mei=Shin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SatoYasuharu en-aut-sei=Sato en-aut-mei=Yasuharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=GionYuka en-aut-sei=Gion en-aut-mei=Yuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HigakiTakaya en-aut-sei=Higaki en-aut-mei=Takaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HarunaTakenori en-aut-sei=Haruna en-aut-mei=Takenori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=FujiwaraTazuko en-aut-sei=Fujiwara en-aut-mei=Tazuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MinouraAkira en-aut-sei=Minoura en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TakaoSoshi en-aut-sei=Takao en-aut-mei=Soshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=OritaYorihisa en-aut-sei=Orita en-aut-mei=Yorihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=KanaiKengo en-aut-sei=Kanai en-aut-mei=Kengo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=TaniguchiMasami en-aut-sei=Taniguchi en-aut-mei=Masami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=NishizakiKazunori en-aut-sei=Nishizaki en-aut-mei=Kazunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=OkanoMitsuhiro en-aut-sei=Okano en-aut-mei=Mitsuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= affil-num=1 en-affil=Department of Otolaryngology-Head & Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Otolaryngology-Head & Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Pathology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Pathology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Otolaryngology-Head & Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Otolaryngology-Head & Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Otolaryngology-Head & Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Public Health, Showa University School of Medicine kn-affil= affil-num=9 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Otolaryngology-Head and Neck Surgery, Kumamoto University kn-affil= affil-num=11 en-affil=Department of Otorhinolaryngology-Head & Neck Surgery, Kagawa Prefectural Central Hospital kn-affil= affil-num=12 en-affil=Clinical Research Center for Allergy and Rheumatology, National Hospital Organization Sagamihara National Hospital kn-affil= affil-num=13 en-affil=Department of Otolaryngology-Head & Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=14 en-affil=Department of Otolaryngology-Head & Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Chronic rhinosinusitis kn-keyword=Chronic rhinosinusitis en-keyword=Eosinophils kn-keyword=Eosinophils en-keyword=IgG4 kn-keyword=IgG4 en-keyword=Nasal polyps kn-keyword=Nasal polyps en-keyword=Severity kn-keyword=Severity END start-ver=1.4 cd-journal=joma no-vol=68 cd-vols= no-issue=4 article-no= start-page=249 end-page=252 dt-received= dt-revised= dt-accepted= dt-pub-year=2014 dt-pub=201408 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Tracheal Stenosis Caused by Unnoticed Foreign Bodies en-subtitle= kn-subtitle= en-abstract= kn-abstract=We describe an extremely rare case of tracheal stenosis caused by unnoticed microscopic fiber-like foreign bodies.

Tracheotomy and biopsy were performed. Histologically, the lesion showed chronic inflammation with a deposition of fiber-like foreign bodies. The patient had no history of trauma or inhalation injury, but had undergone intratracheal intubation on 4 occasions. The lesion was incised using semiconductor laser photoresection, and the postoperative course was good. To the best of our knowledge, this represents the first report in the English literature of tracheal stenosis caused by unnoticed foreign bodies. The origin of these fiber-like foreign bodies remains unclear but might be related to chronic inflammation resulting from intratracheal intubations. en-copyright= kn-copyright= en-aut-name=OgawaraYuya en-aut-sei=Ogawara en-aut-mei=Yuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TachibanaTomoyasu en-aut-sei=Tachibana en-aut-mei=Tomoyasu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OritaYorihisa en-aut-sei=Orita en-aut-mei=Yorihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=UchinoKaori en-aut-sei=Uchino en-aut-mei=Kaori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=WaniYoji en-aut-sei=Wani en-aut-mei=Yoji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NagahiroItaru en-aut-sei=Nagahiro en-aut-mei=Itaru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MatsuyamaYuko en-aut-sei=Matsuyama en-aut-mei=Yuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=AbeIku en-aut-sei=Abe en-aut-mei=Iku kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=FujisawaMasayoshi en-aut-sei=Fujisawa en-aut-mei=Masayoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=NishizakiKazunori en-aut-sei=Nishizaki en-aut-mei=Kazunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil= kn-affil=Department of Otolaryngology, Himeji Red Cross Hospital affil-num=2 en-affil= kn-affil=Department of Otolaryngology, Himeji Red Cross Hospital affil-num=3 en-affil= kn-affil=Department of Otolaryngology, Head and Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences affil-num=4 en-affil= kn-affil=Department of Pathology, Himeji Red Cross Hospital affil-num=5 en-affil= kn-affil=Department of Pathology, Himeji Red Cross Hospital affil-num=6 en-affil= kn-affil=Nagahiro Clinic affil-num=7 en-affil= kn-affil=Department of Otolaryngology, Himeji Red Cross Hospital affil-num=8 en-affil= kn-affil=Department of Otolaryngology, Himeji Red Cross Hospital affil-num=9 en-affil= kn-affil=Department of Pathology, Kurashiki Central Hospital affil-num=10 en-affil= kn-affil=Department of Otolaryngology, Head and Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences en-keyword=tracheal stenosis kn-keyword=tracheal stenosis en-keyword=fibrous foreign body kn-keyword=fibrous foreign body en-keyword=intubation kn-keyword=intubation en-keyword=tracheotomy kn-keyword=tracheotomy en-keyword=laser kn-keyword=laser END start-ver=1.4 cd-journal=joma no-vol=8 cd-vols= no-issue=2 article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2013 dt-pub=20130213 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A20 (TNFAIP3) Deletion in Epstein-Barr Virus-Associated Lymphoproliferative Disorders/Lymphomas en-subtitle= kn-subtitle= en-abstract= kn-abstract=A negative regulator of the nuclear factor (NF)-kappa B pathway, A20 (TNFAIP3), is inactivated in several types of lymphomas; particularly in diffuse large B-cell lymphoma (DLBCL), classical Hodgkin's lymphoma, and extranodal marginal zone lymphoma of the mucosa-associated lymphoid tissue. These findings suggest that the NF-kappa B activation is related to A20 inactivation. Recently, A20 inactivation has also been observed in Epstein-Barr virus (EBV)-related lymphomas; however, this occurrence has not been well investigated. Moreover, NF-kappa B is a key molecule in activated B-cell-like (ABC)-type DLBCL; EBV-associated DLBCL is of the ABC type. Therefore, we focused on A20 deletions in EBV-associated lymphoproliferative disorders/lymphomas. Using fluorescent in situ hybridization analysis, A20 deletions were identified in 4 of 13 samples from patients with pyothorax-associated lymphoma (PAL) (31%), 3 of 20 samples from nasal-type NK/T cell lymphomas (NKTLs) (15%), 1 of 8 samples of EBV-positive DLBCL of the elderly (DLBCL-e) (13%), but not in any of the 11 samples from individuals with methotrexate-related lymphoproliferative disorder (MTX-LPD) (0%). Among the samples with A20 deletions, EBV latent membrane protein 1 (LMP-1) expression was detected in all 4 of the PAL samples with A20 deletions and in the DLBCL-e sample with an A20 deletion, but not in any of the 3 NKTL samples. This finding indicated that A20 deletions were not directly related to the EBV latency pattern of lymphomas, although such deletions might be related to the diagnostic category. Immunohistologically, the A20 protein was absent in 2 (15%) of the13 PAL samples, 1 (9%) of 11 MTX-LPD samples, and in none of the 20 NKTL (0%) or 8 DLBCL-e samples. In conclusion, A20 deletion and/or dysfunctional expression are frequently associated with PALs, and A20 abnormalities may be related to the pathogenesis of PAL. en-copyright= kn-copyright= en-aut-name=AndoMidori en-aut-sei=Ando en-aut-mei=Midori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SatoYasuharu en-aut-sei=Sato en-aut-mei=Yasuharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakataKatsuyoshi en-aut-sei=Takata en-aut-mei=Katsuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NomotoJunko en-aut-sei=Nomoto en-aut-mei=Junko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NakamuraShigeo en-aut-sei=Nakamura en-aut-mei=Shigeo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OhshimaKoichi en-aut-sei=Ohshima en-aut-mei=Koichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TakeuchiTamotsu en-aut-sei=Takeuchi en-aut-mei=Tamotsu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OritaYorihisa en-aut-sei=Orita en-aut-mei=Yorihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KobayashiYukio en-aut-sei=Kobayashi en-aut-mei=Yukio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=YoshinoTadashi en-aut-sei=Yoshino en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil= kn-affil=Okayama Univ, Dept Pathol, Grad Sch Med Dent & Pharmaceut Sci affil-num=2 en-affil= kn-affil=Okayama Univ, Dept Pathol, Grad Sch Med Dent & Pharmaceut Sci affil-num=3 en-affil= kn-affil=Okayama Univ, Dept Pathol, Grad Sch Med Dent & Pharmaceut Sci affil-num=4 en-affil= kn-affil=Natl Canc Ctr, Div Hematol affil-num=5 en-affil= kn-affil=Nagoya Univ Hosp, Dept Pathol & Clin Lab affil-num=6 en-affil= kn-affil=Kurume Univ, Sch Med, Dept Pathol affil-num=7 en-affil= kn-affil=Gifu Univ, Grad Sch Med, Dept Immunopathol affil-num=8 en-affil= kn-affil=Okayama Univ, Dept Otolaryngol Head & Neck Surg, Grad Sch Med Dent & Pharmaceut Sci affil-num=9 en-affil= kn-affil=Natl Canc Ctr, Div Hematol affil-num=10 en-affil= kn-affil=Okayama Univ, Dept Pathol, Grad Sch Med Dent & Pharmaceut Sci END start-ver=1.4 cd-journal=joma no-vol=133 cd-vols= no-issue=9 article-no= start-page=951 end-page=956 dt-received= dt-revised= dt-accepted= dt-pub-year=2013 dt-pub=201309 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The engraftment and differentiation of transplanted bone marrow-derived cells in the olfactory bulb after methimazole administration en-subtitle= kn-subtitle= en-abstract= kn-abstract=Conclusion: Bone marrow-derived cells can be engrafted in the olfactory bulb and a few cells can differentiate into mitral/tufted cells in the olfactory bulb. Objectives: To investigate whether bone marrow-derived cells can be engrafted into the olfactory bulb and differentiate into neurons and glial cells after methimazole administration. Methods: Bone marrow of GFP (green fluorescence protein) mice was transplanted into lethally irradiated recipient mice. Immunostaining was performed to confirm the cell types of bone marrow-derived cells expressing GFP. Results: GFP-positive cells were observed in the olfactory bulb at 2 days after methimazole administration. The number of dendritic GFP-positive cells increased up to 30 days after methimazole administration and then decreased. Double immunostaining for GFP and Iba1 or TBX21 showed that a large population of the GFP-positive cells had characteristics of microglia/macrophages and a few cells had characteristics of mitral/tufted cells. en-copyright= kn-copyright= en-aut-name=NodaYohei en-aut-sei=Noda en-aut-mei=Yohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NishizakiKazunori en-aut-sei=Nishizaki en-aut-mei=Kazunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YoshinobuJunko en-aut-sei=Yoshinobu en-aut-mei=Junko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OritaYorihisa en-aut-sei=Orita en-aut-mei=Yorihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TsujigiwaHidetsugu en-aut-sei=Tsujigiwa en-aut-mei=Hidetsugu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YamadaMasao en-aut-sei=Yamada en-aut-mei=Masao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil= kn-affil=Okayama Univ, Grad Sch Med Dent & Pharmaceut Sci, Dept Otolaryngol Head & Neck Surg affil-num=2 en-affil= kn-affil=Okayama Univ, Grad Sch Med Dent & Pharmaceut Sci, Dept Otolaryngol Head & Neck Surg affil-num=3 en-affil= kn-affil=Okayama Univ, Grad Sch Med Dent & Pharmaceut Sci, Dept Otolaryngol Head & Neck Surg affil-num=4 en-affil= kn-affil=Okayama Univ, Grad Sch Med Dent & Pharmaceut Sci, Dept Otolaryngol Head & Neck Surg affil-num=5 en-affil= kn-affil=Okayama Univ, Grad Sch Med Dent & Pharmaceut Sci, Dept Oral Pathol & Med affil-num=6 en-affil= kn-affil=Okayama Univ, Grad Sch Med Dent & Pharmaceut Sci, Dept Virol en-keyword=Transplantation kn-keyword=Transplantation en-keyword=regeneration kn-keyword=regeneration en-keyword=olfaction kn-keyword=olfaction en-keyword=mitral cells kn-keyword=mitral cells en-keyword=microglia kn-keyword=microglia END start-ver=1.4 cd-journal=joma no-vol=8 cd-vols= no-issue=2 article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2013 dt-pub=20130228 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Clinicopathologic Analysis of Localized Nasal/Paranasal Diffuse Large B-Cell Lymphoma en-subtitle= kn-subtitle= en-abstract= kn-abstract=Diffuse large B-cell lymphoma (DLBCL) comprises 2 molecularly distinct subgroups of non-germinal center B-cell-like (non-GCB) and germinal center B-cell-like (GCB) DLBCLs, with the former showing relatively poor prognosis. In the present study, we analyzed the clinicopathological features of 39 patients with localized nasal/paranasal DLBCL. Immunohistochemistry-based subclassification revealed that 11 patients (28%) were of the GCB-type according to Hans' algorithm and 11 (28%) were of the GCB-type according to Choi's algorithm. According to both Hans' and Choi's algorithms, the non-GCB type was predominant. Nevertheless, prognosis was good. Overall survival did not differ significantly between the GCB and non-GCB subgroups (Hans' algorithm: p = 0.57, Choi's algorithm: p = 0.99). Furthermore, the prognosis of localized nasal/paranasal DLBCL was better than that of other localized extranodal DLBCLs. The prognosis of extranodal DLBCL is usually considered poorer than that of nodal DLBCL. However, in our study, no difference was noted between patients with localized nasal/paranasal DLBCL and patients with localized nodal DLBCL. In conclusion, although the non-GCB subtype is thought to show poor prognosis, in our study, the prognosis for localized nasal/paranasal DLBCL patients was good irrespective of subclassification. en-copyright= kn-copyright= en-aut-name=TodaHiroko en-aut-sei=Toda en-aut-mei=Hiroko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SatoYasuharu en-aut-sei=Sato en-aut-mei=Yasuharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakataKatsuyoshi en-aut-sei=Takata en-aut-mei=Katsuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OritaYorihisa en-aut-sei=Orita en-aut-mei=Yorihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=AsanoNaoko en-aut-sei=Asano en-aut-mei=Naoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YoshinoTadashi en-aut-sei=Yoshino en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil= kn-affil=Okayama Univ, Grad Sch Med Dent & Pharmaceut Sci, Dept Pathol affil-num=2 en-affil= kn-affil=Okayama Univ, Grad Sch Med Dent & Pharmaceut Sci, Dept Pathol affil-num=3 en-affil= kn-affil=Okayama Univ, Grad Sch Med Dent & Pharmaceut Sci, Dept Pathol affil-num=4 en-affil= kn-affil=Okayama Univ, Grad Sch Med Dent & Pharmaceut Sci, Dept Otolaryngol Head & Neck Surg affil-num=5 en-affil= kn-affil=Nagoya Univ Hosp, Dept Clin Lab affil-num=6 en-affil= kn-affil=Okayama Univ, Grad Sch Med Dent & Pharmaceut Sci, Dept Pathol END start-ver=1.4 cd-journal=joma no-vol=67 cd-vols= no-issue=4 article-no= start-page=265 end-page=269 dt-received= dt-revised= dt-accepted= dt-pub-year=2013 dt-pub=201308 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Large Ulceration of the Oropharynx Induced by Methotrexate-Associated Lymphoproliferative Disorders en-subtitle= kn-subtitle= en-abstract= kn-abstract=We present a case of a 67-year-old Japanese man with a serious oropharyngeal ulceration that at first seemed to be destructive malignant lymphoma or oropharyngeal carcinoma.

Study Design: We investigated LCR on IDS in 40 patients with proliferative lymphatic disorders (23 with B cell lymphoma, 13 with reactive lymphoid lesions, 2 with T cell lymphoma and 2 with Hodgkin's lymphoma). In addition, the results of flow cytometry (FCM) were compared in 34 of these patients. Results: On IDS, LCR was detected in 21 of 23 patients (91.3%) with B cell lymphoma. On FCM, it was detected in 15 of 21 patients (71.4%) with B cell lymphoma. Neither IDS nor FCM showed LCR in any patients with reactive lesions, T cell lymphoma or Hodgkin's lymphoma. Conclusion: IDS facilitated the detection of LCR with a single specimen under morphological observation. The application of this procedure may improve the accuracy of cytological diagnosis. en-copyright= kn-copyright= en-aut-name=ShimouraYasumasa en-aut-sei=Shimoura en-aut-mei=Yasumasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SatoYasuharu en-aut-sei=Sato en-aut-mei=Yasuharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakataKatsuyoshi en-aut-sei=Takata en-aut-mei=Katsuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OritaYorihisa en-aut-sei=Orita en-aut-mei=Yorihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NakamuraSatoko en-aut-sei=Nakamura en-aut-mei=Satoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ManoShyouhe en-aut-sei=Mano en-aut-mei=Shyouhe kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YoshinoTadashi en-aut-sei=Yoshino en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil= kn-affil=Kagawa Prefectural Cent Hosp, Clin Lab, Dept Pathol affil-num=2 en-affil= kn-affil=Okayama Univ, Grad Sch Med Dent & Pharmaceut Sci, Dept Pathol affil-num=3 en-affil= kn-affil=Okayama Univ, Grad Sch Med Dent & Pharmaceut Sci, Dept Pathol affil-num=4 en-affil= kn-affil=Okayama Univ, Grad Sch Med Dent & Pharmaceut Sci, Dept Otolaryngol Head & Neck Surg affil-num=5 en-affil= kn-affil=Kagawa Prefectural Cent Hosp, Clin Lab, Dept Pathol affil-num=6 en-affil= kn-affil=Kagawa Prefectural Cent Hosp, Clin Lab, Dept Pathol affil-num=7 en-affil= kn-affil=Okayama Univ, Grad Sch Med Dent & Pharmaceut Sci, Dept Pathol en-keyword=Cytology kn-keyword=Cytology en-keyword=Immunocytochemical kn-keyword=Immunocytochemical en-keyword=double staining kn-keyword=double staining en-keyword=Immunoglobulin light-chain restriction kn-keyword=Immunoglobulin light-chain restriction en-keyword=Lymph node kn-keyword=Lymph node en-keyword=B cell lymphoma kn-keyword=B cell lymphoma en-keyword=Flow cytometry kn-keyword=Flow cytometry END start-ver=1.4 cd-journal=joma no-vol=67 cd-vols= no-issue=1 article-no= start-page=61 end-page=64 dt-received= dt-revised= dt-accepted= dt-pub-year=2013 dt-pub=201302 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Papillary Thyroid Carcinoma Arising from a Median Ectopic Thyroid with No Thyroglossal Duct Remnant en-subtitle= kn-subtitle= en-abstract= kn-abstract=Thyroid carcinomas arising from ectopic thyroid tissue are uncommon;most of them arise from thyroid tissue in thyroglossal cysts.
