title: [Gastrointestinal vascular malformation].
abstract: Dieulafoy's disease, described in 1898, has been considered a rarity. Morphologically is represented by single, large and tortuous artery located in the gastric submucosa and overlying by submucosal defect that is responsible for severe digestive bleeding. We report two cases of this gastrointestinal vascular malformation: one in the stomach and the other in the jejunum. We believe that better knowledge of this lesion and more reports about it are important to decrease the mortality rate in those cases.
