Gastritis cystica polyposa in an unoperated stomach

SummaryGastritis cystica polyposa is relatively rare and characterized by polypoid hyperplasia and cystic dilatation of the gastric glands in stomach. Most cases are related to previous gastric surgeries, but a few cases have been reported in unoperated stomachs. We present a 34-year-old man who had anemic symptoms with melena and exertional dyspnea for 3 weeks. He denied any surgical history. An esophagogastroduodenoscopy revealed diffuse giant folds extending from the lower to the upper body of the stomach with nodularity and no obvious bleeding site. A pathologic diagnosis of a punch biopsy specimen from the giant folds revealed only moderately active chronic inflammation with a high Helicobacter pylori density. After serial studies, the patient received a whole layer gastric biopsy during a laparoscopy. Gastritis cystica polyposa was diagnosed on the pathology report. Our present case highlights the rare clinical and endoscopic condition of gastritis cystica polyposa in an unoperated stomach.
