Gastritis cystica polyposa in an unoperated stomach, a case report

Abstract

Gastritis cystica polyposis (GCP) is a rare benign hyperplastic polypoid neoplasm that usually occurs on the gastric side of anastomoses in patients who have previously undergone gastroenterostomy surgery. Only few cases of GCP have been reported in a previously unoperated stomach. Here we present a 73-year-old female who on investigation for altered bowel habits was found to have a gastric polyp diagnosed as GCP. Both endoscopic and radiological findings are non-specific, and diagnosis depends on histopathological evaluation of the lesion. Histologically the lesion showed a hyperplastic polyp with cystically dilated foveolar and glandular epithelium extending into the submucosa surrounded by disorganised bundles of smooth muscle and without any evidence of cytologic atypia, typical of GCP. Although benign, an associated with gastric carcinoma has been described.
