Abstract

Gastritis cystica profunda (GCP) is a rare disease in which hyperplastic and cystic dilatation of the gastric mucous glands extend into the tissues beneath the submucosa. GCP is mainly observed at the site of a gastroenterostomy; however, it may occur in the stomach without a previous history of surgery. GCP may present not only as a submucosal tumor or as solitary or diffuse polyps but also rarely as a giant gastric mucosal fold. In a patient without a previous history of surgery, GCP presents mainly as a sessile polypoid protrusion or as a submucosal tumor. In addition, GCP presents with non-specific symptoms and is most commonly found incidentally. We present a case of GCP that developed upper gastrointestinal bleeding and showed a long stalk and a focal ulcerative lesion on the surface of a polyp that developed in the stomach without a history of previous surgery. This lesion was removed by the use of an endoscopic polypectomy and was histologically diagnosed as GCP. (Korean J Gastrointest Endosc 2007;35:186-189)
