Various types of malignant tumor, such as lymphoma and carcinoma, arise in the terminal ileum,1 but adenoma is rare in this segment of the small intestine. Two cases are reported in which an adenoma in the terminal ileum was removed by EMR. Endoscopic and stereomicroscopic findings are presented. The clinical benefit of EMR for ileal adenoma is discussed. CASE REPORT Case 1 A 65-year-old man presented with hematochezia. There was a history of laparotomy 24 years earlier for duodenal ulcer. The family history was unremarkable. At a prior colonoscopy, 5 colonic polyps and one ileal polyp were found, and the patient was referred for further evaluation and treatment.
