Solitary ileal lipoma presenting with ileocolic intussusception: an unusual cause of enteritis cystica profunda.

We report a 63-year-old man who presented with a history of intermittent vague abdominal pain, diarrhea, and weight loss. Colonofibroscopic examination disclosed an ileocolic intussusception with a polypoid tumor on the leading edge of the intussusception. Both double contrast barium enema and computerized tomography of the abdomen confirmed this finding. The excised specimen had an ulcerated ileal lipoma with enteritis cystica profunda on the overlying epithelium.
