RESUMO

La lesión de Dieulafoy es una rara anomalía vascular causa de hemorragias gastrointestinales masivas. Se caracteriza por el sangrado de una arteriola submucosa a través de una erosión en la mucosa, por otra parte normal. Aunque la lesión de Dieulafoy fue inicialmente descrita en el estómago y el tracto digestivo superior, también se han comunicado casos en el colon, recto y en canal anal. Publicamos el primer caso de lesión de Dieulafoy en la vesícula biliar que se presentó como una hemorragia peritoneal masiva. Describimos las características clínico-patológicas de esta inusual entidad, así como el abordaje de su diagnóstico y tratamiento(AU)


Dieulafoy's lesion is an uncommon vascular anomaly causing massive gastrointestinal hemorrhage, characterized by bleeding from an arteriole that protrudes through a tiny mucosal defect. Although Dieulafoy's lesion was initially described in the stomach and upper gastrointestinal tract, cases have also been reported in the colon, rectum and anal canal. We report the first case of Dieulafoy's lesion in the gallbladder, which presented as massive peritoneal bleeding. We describe the clinical and pathological characteristics of this unusual entity, as well as the approach to its diagnosis and treatment (AU)
