Abstract

Gastritis cystica polyposa (GCP) is a rare lesion characterized by hyperplastic and cystic dilatation of the gastric mucosal glands infiltrating into the underlying submucosa. In most cases, it develops in patients who have undergone a gastroenterectomy, but can occasionally be found in an unoperated stomach. GCP may present as a submucosal tumor or polyp, and rarely as a giant gastric mucosal fold. We experienced a case of GCP that presented as a hyperplastic polyp, and it was unrelated to any gastric surgery. Upper endoscopy revealed the presence of a subpedunculated polyp in the posterior wall of the antrum. The lesion was successfully removed by endoscopic mucosal resection and diagnosed as a GCP.
