title: Severe bleeding from submucosal lipoma of the duodenum.
abstract: Two patients with a duodenal lipoma had severe gastrointestinal bleeding. Duodenal lipoma is relatively rare and an even rarer source of severe gastrointestinal bleeding. Endoscopy and routine radiological examination of the gastrointestinal tract may suggest the diagnosis, but computed tomography allows a definitive preoperative diagnosis. Surgery is indicated in order to avoid complications.
