Dieulafoy Lesion of the Colon: A Rare Finding During Colonoscopy

Dieulafoy lesions are common dilated submucosal vessels that can present with gastrointestinal (GI) bleeding. These lesions are usually found in the stomach or esophagus and colonic Dieulafoy lesions are very rare. Clinical presentation can vary from mild non-threatening GI bleeding to massive and recurrent hemorrhage. Here, we discuss a case of a 71-year-old female patient who presented with a bright red bleed per rectum. Colonoscopy was performed, which revealed a bleeding Dieulafoy lesion in the descending colon with clotted blood in the transverse and descending colon. In this article, we will also review the literature related to the epidemiology, clinical presentation, diagnosis, and management of Dieulafoy lesions.
