The patient was a 74-year-old woman whose chief complaints were anemia and black stools. Abdominal contrast-enhanced computed tomography was performed to determine the cause of anemia, and localized jejunal wall thickening and surrounding lymph node enlargement were seen. On transoral double-balloon enteroscopy, ulceration was seen around the entire circumference of the jejunum. Ulcer margins were somewhat thick. The margin was regular and wall expansion was good. Blood vessels were exposed at the ulcer floor, and hemostasis was achieved by clipping. T-cell lymphoma was diagnosed from histopathological examination of a biopsy specimen. Enteropathy-associated T-cell lymphoma type Ⅱ was diagnosed from a specimen obtained from partial resection of the small bowel. This report describes a case of enteropathy-associated T-cell lymphoma diagnosed after intestinal bleeding.
