Aneurysms of gastric vessels (Dieulafoy`s disease, caliber-persistent artery) are thought to be of malformative rather than degenerative origin. They are usually single, located in the submucosa, usually on the lesser curvature, and characterized by a large tortuous vessel surmounted by a small defect in the overlying mucosa. When the lesion perforates, massive and sometimes fatal hemorrhage may result. Here, we report one patient with massive upper gastrointestinal bleeding who was treated by surgical resection and later diagnosed with dieulafoy`s malformation in the stomach. Thus, physicians should bear in mind dieulafoy’s lesion when they are faced with massive upper gastrointestinal bleeding.
