Abstract

Gastritis cystica polyposa (GCP) is an uncommon lesion that usually develops at the gastroenterostomy site. A 57-year-old man visited a hospital with a complaint of melena. He did not have any surgical history or past medical history. Endoscopy was performed to evaluate the cause of melena, and a polypoid cystic mass in the stomach was found on an endoscopy and endoscopic ultrasonography. The polypoid cystic mass did not show any enhancing solid portion on a computed tomography. The gastric lesion was conclusively confirmed as GCP through endoscopic submucosal dissection. We report a rare case of GCP that occurred in an unoperated stomach.

  Fig. 1 A 57-year-old man with gastritis cystica polyposa in the unoperated stomach, which was confirmed by an endoscopic mucosal dissection. A. The initial endoscopic image shows a polypoid mass of 2.4 cm in size with mucosal ulceration and erythema on the mass. Submucosal hemorrhage is shown in the adjacent gastric mucosa. B. Erythema of gastric mucosa and ulceration on the surface of the polypoid mass are improved on the follow-up endoscopic image. C. EUS image shows a unilocular, cystic mass in the submucosal layer without any solid component. The mass has a narrow stalk (arrows). D, E. The axial (D) and coronal (E) images of contrast-enhanced CT show a polypoid, cystic mass (arrows) with a well-defined margin on the greater curvature of the stomach. Intact gastric mucosa is seen overlying the mass. F. The gross specimen shows a polypoid mass with a submucosal stroma measuring 2 × 1.8 × 2.5 cm. Cross-sectioning of the specimen reveals a unilocular cyst with a background of pale brown mucoid submucosal stroma. G. On microscopic examination, there is a large submucosal cyst (arrowheads) lined with gastric epithelium. Some elongated gastric glands (arrows) penetrate the muscularis mucosa (Hematoxylin-Eosin stain, × 12.5). Note.-EUS = endoscopic ultrasonography
