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

Background Colonic 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 presentation We 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. Conclusion A 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.
