It is seen most commonly on the lesser curvature of the proximal stomach, causes impressive aerial hemorrhage, and may be difficult to diagnose. It is often recognized only after repeated endoscopy for recurrent bleeding. Endoscopic therapy, such as thermal coagulation, is typically effective for control of bleeding.
