Gastric polyps can be categorized as hyperplastic or adenomatous. Hyperplastic gastric polyps account for 28~77% of gastric polyps. Adenomatous polyps are recommended for removal due to their premalignant potential. However, there is no consensus on treatment and endoscopic surveillance of hyperplastic gastric polyps. The incidence of malignant neoplasms found in hyperplastic polyps has been reported to be about 2.1%; most of the reported cases of hyperplastic gastric polyps with malignant transformation were histologically well differentiated. We report a rare case of a gastric hyperplastic polyp with a signet ring cell carcinoma, with a review of the literature.
