Gastritis cystic polyposa is a rare and peculiar polypoid lesion arising at a gastroenterostomy

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.
