Abstract

Lipomas arise in the colon with an incidence of up to 4.4%. Usually asymptomatic, they can reach big dimensions causing bleeding, obstruction, intussusception and prolapse. The occurrence of adenomas overlying a colonic lipoma is rare. The authors report a case of a giant sigmoid lipoma with a wide villous adenoma in the lining mucosa. They also suggest a pathogenetic hypothesis of this event.
