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

AbsractGastritis cystic polyposa is a rare and peculiar polypoid lesion arising at a gastroenterostomysite, and almost always on the gastric side. It is characterized by elongationof the gastric foveolae along with hyperplasia and cystic dilatation of the gastricglands extending into the submucosal layer. Esophagogastroduodenoscopy in a47-year-old woman without any history of gastric operation revealed a pedunculatedpolyp approximately 2 cm in diameter, in a background of erythematous gastric foldsalong the anterior wall of the fundus. Polypectomy was performed, with endoscopicimpression of hyperplastic or fundic gland polyp, without any complications.Histopathological findings were consistent within gastritis cystic polyposa(GCP). Amild Helicobacter pylori colonization in gastric pits was seen. GCP could occur in anunoperated stomach and treated by endoscopic polypectomy. However, removal andhistopathologic confirmation of these lesions are necessary.
