A Case of Bleeding Gastric Villous Adenoma Treated with Endoscopic Mucosal Resection / 대한내과학회지

ABSTRACT

Villous adenomas of the stomach are rare, although they more frequently occur in the colon and rectum. Clinical symptoms are similar to gastric polyps, but acute or chronic bleeding with anemia occurs frequently. The size of tumors varies between 4 and 6 cm, and the malignant potential is greater when the tumor is larger. Complete resection with surgery or endoscopic resection is the treatment of choice. Endoscopic findings revealed a dome-like or pedunculated appearance. Microscopically, the tumor was composed of long fronds and papillations covered by columnar epithelia with a reduced number of goblet cells. We report a case of polyps with chronic intermittent and acute bleeding for 6 months, which was alleviated by endoscopic mucosal resection and was confirmed as a villous adenoma.
