A 77-year-old woman was admitted to our hospital with anemia and anorexia. Neither gastrointestinal endoscopy nor computed tomography showed by abnormal findings; however, a capsule endoscopy, performed to detect obscure gastrointestinal bleeding, revealed a tumor in the ileum. When we tried to take biopsies of the ileal tumor by push enteroscopy via the anus, we found another tumor in the transverse colon. On exploration, tumors were identified in the ileum and the transverse colon. Thus, we resected the ileum and transverse colon with regional lymph node dissection. Histologic sections from both the ileum and colon revealed moderately differentiated adenocarcinomas with no lymph node metastasis.
