RESUMO
Massive low gastrointestinal bleedings are often difficult diagnostically and in terms of management. Sometimes, it is not possible to identify the bleeding point after performing diverse diagnostic tests and the patient undergoes a blind subtotal colectomy. With rectal bleeding, this form of surgery is completely useless, as it will not solve the cause of the haemorrhage. The Dieulafoy lesion has been widely described in the stomach, but in the rectum is a very rare entity that can cause massive lower gastrointestinal bleeding. In the literature, there are only 25 described cases of rectal Dieulafoy lesion.
