title: [Dieulafoy colonic ulcer. A rare cause of lower gastrointestinal hemorrhage].
abstract: Dieulafoy's disease is an unusual cause of gastrointestinal hemorrhage, reported to account for less than 2% of acute gastrointestinal bleeding episodes. Bleeding occurs from a defect in an unusually large submucosal artery, through a minute mucosal erosion. Endoscopic diagnosis is sometimes difficult, but primary endoscopic therapy may be successful and should be attempted. In most cases the lesion is found in the proximal stomach. Sixteen cases of Dieulafoy's lesion located in the colon have been reported in the literature but only nine have been confirmed by histology. We present the case of a 63 year-old male with Dieulafoy's lesion of the transverse colon which was diagnosed by endoscopy and confirmed by histology.
