gastric polyps

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
