Villous adenoma arising in Meckel's diverticulum
1Department of Pathology, Cell Biology and Anatomy, Thomas Jefferson University, Philadelphia, Pennsylvania 19107-5244, USA.
Abstract:
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.

Microvilli
These microvilli are predominantly present in cells lining the small intestine, kidney tubules, and certain cells in the respiratory and reproductive systems. By significantly expanding the surface area of the cell membrane, microvilli enhance the cell's capacity to...
