Arteriovenous malformations are degenerative lesions of the gastrointestinal tract that occur with a frequency that increases with increasing age. Although the bleeding caused by arteriovenous malformations is typically chronic, slow, intermittent and recurrent, 15% of patients with arteriovenous malformations present with massive bleeding. Any part of the gastrointestinal tract can be involved and arteriovenous malformations usually appear on endoscopy as either flat or elevated discrete bright red mucosal lesions. There are a few cases of colonic arteriovenous venous malformations with a polypoid appearance with some of their endoscopic treatments resulting in profuse bleeding from the remnant stalk. We encountered a case of a polypoid arteriovenous malformation in the colon of a 69-year-old patient with active gastrointestinal bleeding. The patient was treated successfully by an endoscopic polypectomy with a detachable snare. (Korean J Gastrointest Endosc 2006;33:313⁣317)
