Lesión de Dieulafoy de vesícula biliar como causa de hemobilia con hemoperitoneo / Dieulafoy's lesion of the gallbladder as a cause of hemobilia with hemoperitoneum

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)

[Atypical or bizarre leiomyoma of the scrotum. Report of one case and bibliographic review]. / Leiomioma atípico o bizarro de escro- to. Presentación de un caso y revi- sión de la literatura.

OBJECTIVES: To describe the clinicopathological characteristics of the scrotal bizarre leiomyoma in order to increase our understanding, and avoid the possibility of erroneous diagnosis and treatment. RESULTS: We report the case of a 43 year-old patient with a pendulous nodular scrotal tumour, which after microscopic study could be seen to be of smooth muscular origin, corresponding, because of its peculiar histological characteristics, to the rare variety called atypical or symplasmic bizarre leiomyoma. CONCLUSION: Although it is a form of leiomyoma which is extremely infrequently found in the scrotum, it is necessary to know it can occur and to know that we are dealing with a benign tumour that should be treated as such.
