Abstract
Dieulafoy's lesion, also known as a caliber-persistent artery of the stomach, is an uncommon cause of GI bleeding; it accounts for only 2% of episodes of acute and chronic bleeding.1,2 This mucosal lesion, usually occurring along the lesser curvature of the proximal stomach, is small and shallow but can be associated with a massive, life-threatening hemorrhage. Dieulafoy's lesion may be difficult to diagnose, especially when bleeding is absent. Although initial descriptions were based on surgically resected specimens, endoscopy is a sensitive and accurate means of diagnosis.
