Gastrointestinal bleeding due to a dieulafoy lesion in the duodenum: A case report

Dieulafoy’s ulcer is a rare but potentially life, threatening vascular anomaly of the gastrointestinal tract. It is characterized by the erosion of the wall of a submucosal artery, most commonly in the stomach, though it can also occur elsewhere along the digestive tract. While the gastric location is most frequently reported, extragastric cases, particularly in the small intestine, have also been described. This lesion is often associated with significant gastrointestinal bleeding, which may be severe or even fatal. Prompt diagnosis is essential to ensure appropriate therapeutic intervention, usually endoscopic, and to prevent serious complications such as perforation or massive hemorrhage. We present a rare case of Dieulafoy’s ulcer located in the duodenum, an uncommon site, and discuss the diagnostic and therapeutic challenges it poses, as well as its relevance in the management of gastrointestinal bleeding.
