Abstract:
A 65-year-old man had abdominal pain and night sweat for several weeks. He had lost weight and also reported black stools. Anemia of iron deficiency was found in laboratory tests. Further investigation revealed a stenosing process in the small intestine as source of bleeding. High grade non-Hodgkins' lymphoma was diagnosed histologically in the resected bowel segment and the mesenteric lymph nodes. Further staging did not reveal further manifestations of lymphoma. Polychemotherapy and subsequent irradiation were administered.
