Villous adenoma arising in Meckel's diverticulum
1Department of Pathology, Cell Biology and Anatomy, Thomas Jefferson University, Philadelphia, Pennsylvania 19107-5244, USA.
This report details the first documented case of a villous adenoma in a Meckel
Area of Science:
- Gastroenterology and Surgical Pathology
Background:
- Meckel's diverticulum is a congenital anomaly of the small intestine.
- Villous adenomas are neoplastic polyps with a high risk of malignant transformation.
- Ulcerative colitis is a chronic inflammatory bowel disease.
Observation:
- A 21-year-old male with ulcerative colitis presented with severe abdominal pain and bleeding.
- During surgery for ulcerative colitis, a Meckel's diverticulum was identified.
- The diverticulum contained a villous adenoma with minimal dysplasia, originating from gastric mucosa.
Findings:
- The first documented instance of a villous adenoma within a Meckel's diverticulum without concurrent carcinoma.
- The adenoma arose from heterotopic gastric epithelium within the diverticulum.
- Surgical resection of the Meckel's diverticulum and its adenoma was successfully performed.
Implications:
- Highlights the potential for neoplastic development, specifically villous adenomas, in Meckel's diverticula.
- Suggests the importance of examining Meckel's diverticula during abdominal surgery, even in the absence of typical symptoms.
- Contributes to understanding the diverse pathologies associated with Meckel's diverticula and heterotopic tissues.

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...
