title: [Acute abdomen due to hemoperitoneum as the first manifestation of a liver tumor. Report of four cases (author's transl)].
abstract: Four cases of spontaneous acute hemoperitoneum due to rupture of a liver tumor are presented. The resulting acute abdomen was the first manifestation of the neoplasia. The four tumors corresponded histopathologically to a cavernous hemangioma, a bening adenoma related to anabolizing androgens, and two hepatocarcinomas in cirrhotic livers. All of the patients presented abdominal pain and shock, the characteristics of which are described in this report. One of the patients died due to cardiac arrest before surgical treatment. Emergency surgery was performed on the other three, consisting of left hepatic lobectomy and ligature of the hepatic artery for the hemengioma, and segmented hepatectomy for the adenoma and the hepatocarcinoma. Only the patient with benign tumor survived. Lastly, the authors review the literature, commenting on the clinical, physiopathologic, therapeutic, and prognostic aspects.
