Colonic lipoma intussusception: a case report.

Lipomas are the most common mesenchymal benign tumor of the colon. They are usually asymptomatic but may cause bleeding, obstruction, intussusception, or abdominal pain. The diagnosis can be made by colonoscopy, barium enema examination, and by computed tomography (CT). We have reported a case of large submucosal lipoma of the ascending colon with intestinal obstruction. At laparotomy there was an intussusception descending colon, and subtotal colectomy was performed.
