gastric polyps

Monday 14 February 2005

Definition: Gastric polyps are usually incidental findings.They may be neoplastic or non-neoplastic, with most (80% to 90%) being non-neoplastic.

Gastric polyps may be multiple or solitary, and some complicate polyposis syndromes.

The two main types of non-neoplastic polyps are gastric hyperplastic polyps and fundic gland polyps.

Types

- fundic gland polyp (fundic glandulocystic polyp)
- gastric hyperplastic polyp
- isolated hamartomatous polyp
- inflammatory fibroid polyp
- gastric Peutz-Jeghers polyp
- gastric adenoma / gastric adenomatous adenoma

Predisposition

- adenomatous gastric polyp in familial adenomatous polyposis coli (FAP)
- gastric Peutz-Jeghers polyp in Peutz-Jeghers syndrome
- gastric juvenile polyp in juvenile polyposis
- Cowden disease-associated gastric polyp
- Cronkhite-Canada syndrome-associated gastric polyp
