چکیده
The first well documented case of villous adenoma arising in a Meckel's diverticulum not associated with a carcinoma is reported. A 21 year old man with long history of medically treated ulcerative colitis was admitted to hospital with severe pain and bleeding. Total abdominal colectomy and ileo-anal anastomosis was performed and during this procedure Meckel's diverticulum containing a villous adenoma showing minimal dysplasia was found and resected. The diverticulum was lined partly by ileal and partly by gastric epithelium, and the villous adenoma originated from the gastric mucosa.
