| 抄録 | 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. |

| 抄録 | To evaluate the usefulness of colonoscopy for the detection of ileal involvement in patients with intestinal follicular lymphoma, seventeen patients with intestinal follicular lymphoma who underwent colonoscopy and biopsy sampling from the terminal ileum were enrolled. The patients were divided into 2 groups: cases with ileal involvement (n=6) and cases without ileal involvement (n=11). Patients’ clinical backgrounds were compared between the two groups. Subsequently, 10 board-certified endoscopists independently evaluated the endoscopic pictures and determined whether the ileum was involved with follicular lymphoma. Infiltration of follicular lymphoma cells were identified in 6 patients (35.3%). Cases with positive ileal involvement were diagnosed with follicular lymphoma at a younger age than were cases without ileal involvement (55.4±7.4 vs. 68.1±10.3 years, p=0.011). Macroscopically, in patients with ileal involvement, there were multiple polypoid elevations smaller than 5 mm in 4 cases, single polypoid elevation smaller than 5 mm in 1 case, and single polypoid elevation larger than 5 mm in 1 case. In patients without ileal involvement, there were no lesions in the terminal ileum in 7 cases, and multiple polypoid elevations smaller than 5 mm were seen in 4 cases. The accuracy of the macroscopic evaluation by 10 board-certified endoscopists was 68.8%. Colonoscopy is particularly recommended during the initial workup of patients with follicular lymphoma diagnosed at age ≤ 60 years. The diagnosis of ileal involvement based on morphology alone is difficult; thus, biopsy and pathologic diagnosis are required for accurate diagnosis. |

| 抄録 | Several studies have identified a relationship between myelodysplastic syndrome and Behçetʼs disease (BD), especially intestinal BD, and trisomy 8 appears to play an important role in these disorders. Despite this, only few case reports or series have been reported in gastroenterology, meaning that endoscopic findings and characteristics of intestinal BD have not been clarified yet. In this report, we describe three cases of intestinal BD associated with myelodysplastic syndrome and trisomy 8, and discuss the clinical features and problems of these disorders from a gastroenterology perspective. |

| 抄録 | Whether presence or history of extracolonic primary malignancy is a risk for colorectal neoplasia is not fully known. In this study, 26,452 first-time colonoscopy cases were examined using a colonoscopy database. Among the analyzed subjects, 3,026 (11%) subjects had history or concomitance of extracolonic primary malignancy, while the remaining 23,426 subjects did not. Colorectal neoplasia was observed in 39% of all the subjects. A crude comparison showed that the prevalence of any type of colorectal neoplasia was higher in subjects with extracolonic malignancy than in those without (42% vs. 39%, p＝0.0012). However, after adjusting for confounding factors, the odds ratios (ORs) of subjects with extracolonic malignancy for having colorectal neoplasia, advanced neoplasia, and cancer were all less than 1.0, and all significantly different from those of subjects without extracolonic malignancy. Analysis according to the type of extracolonic malignancy revealed that gastric cancer cases had a significantly lower risk for colorectal advanced neoplasia (OR:0.81;95% CI:0.67-0.99). Among major malignancies, only esophageal squamous cell cancer cases had increased risk for colorectal neoplasia (OR:1.66;95% CI:1.20-2.29). Patients with presence or history of extracolonic malignancy did not carry a higher risk of occurrence of colorectal neoplasia. |
