A rare cause of recurrent lower gastrointestinal hemorrhage due to a rectosigmoid Dieulafoy's lesion

BackgroundColonic Dieulafoy's lesions (DLs) are an extremely rare cause of acute gastrointestinal bleeding. However, it could be presented from self-limiting, mild bleeding episodes up to recurrent, massive life-threatening hemorrhage.Case presentationWe present a case of 9-year-old female with recurrent attacks of hematochezia. The colonoscopy showed actively bleeding Dieulafoy's lesions at the rectosigmoid colon that was successfully managed endoscopically by the application of two hemoclips.ConclusionA prompt and accurate diagnosis in patients with a Dieulafoy's lesion carries paramount importance. A meticulous examination and proper resuscitation are a must because massive, uncontrolled bleeding from this lesion may culminate in the death of the patient fairly quickly.
