Colonic lipomas are the second most common benign tumor of the large bowel; because they are small, they are usually asymptomatic. If there is bleeding or obstruction, however, surgical management is mandatory. These tumors may have a broad-based pedicle, and their diameter is usually less than 3cm. We report a case of colo-colonic intussusception due to certain unique features of this colonic lipoma; a narrow pedicle, giant size, and severe necrosis.
