Heterotopic gastric and pancreatic tissue in large bowel.

Heterotopic gastric and pancreatic tissues rarely involves large bowel. We report the case of a 30-yr-old man who presented with lower gastrointestinal bleeding. The barium enema showed an ulcerated mass lesion at the splenic flexure. Colonoscopy revealed a polypoid ulcerated lesion at the splenic flexure. The resected specimen, on histological examination, showed a polypoid lesion lined by gastric mucosa. The base of the polyp also showed ectopic pancreatic tissue. The patient recovered completely after surgery.
