[Dieulafoy ulcer associated with acute drug-induced gastritis: a rare case]

The lesion in Dieulafoy's disease consists of an unusually large and tortuous artery in the base of an ulcer. The disease is underdiagnosed rather than truly rare and often presents with a massive and potentially fatal, usually repeated, haematemesis. The authors describe a case of Dieulafoy's disease associated with acute drug-induced gastritis whose gravity required, in the case reported, a very serious emergency treatment.
