Giant lipoma of the transverse colon causing colo-colonic intussusceptions.

Lipomas of the colon are relatively rare benign tumors. Colo-colonic intussusception is an unusual complication of colonic lipoma. We report the case of a 79-year-old man who presented with spasmodic, self-limiting abdominal pain associated with rectal bleeding. Colonoscopy revealed a submucosal mass suggestive of a benign tumor but that was too large for endoscopic resection. CT scan demonstrated an endoluminal fatty mass in the transverse colon, typical of lipoma, and suggested colo-colonic intussusception due to the mass. The mass was removed laparoscopically. Recovery was uneventful.
