We report a lipoma of the transverse colon which is rarely encountered. A 61-year-old woman complained of abdominal pain. A barium enema showed a smooth tumor in the transverse colon. Colonofiberscopic findings revealed a submucosal tumor which was elastic-soft with erosion. The CT value of the tumor was -80 Hounsfield unit, identical with that of adipose tissue. From these findings, we diagnosed the tumor as a lipoma of the transverse colon. A partial colectomy was performed and the resected tumor was 3×3×7 cm in size. The histopathological diagnosis was a typical submucosal lipoma.
