Gastritis cystica polyposa in an unoperated stomach, treated by endoscopic polypectomy

ABSTRACT

Gastritis cystic polyposa is a rare and peculiar polypoid lesion arising at a gas-troenterostomy site, and almost always on the gastric side. It is characterized by elongation of the gastric foveolae along with hyperplasia and cystic dilatation of the gastric glands extending into the submucosal layer. Esophagogastroduodenoscopy in a 47-year-old woman without any history of gastric operation revealed a pedunculated polyp approximately 2 cm in diameter, in a background of erythematous gastric folds along the anterior wall of the fundus. Polypectomy was performed, with endoscopic impression of hyperplastic or fundic gland polyp, without any complications. Histopathological findings were consistent within gastritis cystic polyposa[GCP]. A mild Helicobacter pylori colonization in gastric pits was seen. GCP could occur in an unoperated stomach and treated by endoscopic polypectomy. However, removal and histopathologic confirmation of these lesions are necessary
