Dieulafoy-like lesion of the rectum presenting with exsanguinating hemorrhage: successful endoscopic sclerotherapy.

The classic Dieulafoy lesion is a minute gastric mucosal defect that bleeds massively from an exposed artery. Similar lesions have been identified in the small intestine, colon, and rectum. In this report, we describe a patient who presented with an exsanguinating hemorrhage from a small rectal ulcer with a visible vessel. Control of the bleeding was achieved with endoscopic sclerotherapy using absolute alcohol and 1.5% sodium tetradocyl sulfate, with eventual complete healing of the site.
