[Primary vascular tumors of the liver. Analysis of a series of 20 cases].

Twenty patients with one or several primary hepatic vascular tumours were studied. Three of them had an angiosarcoma and the other seventeen had twenty nine hepatic haemangiomas. From these seventeen patients, six corresponded to a giant cavernomatous haemangioma. Symptoms, diagnostic methods and treatment of patients with angiosarcoma (3 cases), giant cavernomatous haemangioma (6 cases) and haemangiomas with size less than 4 cm (11 cases) are separately analyzed. We report our series and a critical revision of diagnosis and treatment of these tumours is made.
