Dieulafoy’s lesion (exulceratio simplex Dieulafoy) is a medical condition characterized by a large tortuous arteriole in the stomach wall that erodes and bleeds. It can cause gastric hemorrhage but is relatively uncommon. It is thought to cause less than 5% of all gastrointestinal bleeds in adults. It was named after French surgeon Paul Georges Dieulafoy who described this condition in his paper Exulceratio simplex: Leçons 1-3 in 1898.
