Gastritis cystica profunda (GCP) is a rare disease in which mature glandular epithelium extends into the muscularis mucosae or below. Mainly GCP lesions developed at gastroenterostomy stomas. We experienced two cases of GCP which were not related with any gastric surgery. The first case was 76-year-old woman who visited for epigastic pain and dyspepsia. The second case was 55-year-old woman complaining right upper quadrant pain. The polyps are found on the greater curvature of the antrum at first case, and on the lesser curvature of the antrum at second case. Each polyp was successfully removed by polypectomy.
