title: Leiomyosarcoma of the inferior vena cava presenting as Budd-Chiari syndrome.
abstract: A case of a 72-year-old male with a leiomyosarcoma of the inferior vena cava causing Budd-Chiari syndrome is described. Percutaneous decompression of the portal system was attempted but with no success. At autopsy, a large tumor arising from and completely obstructing the inferior vena cava was found, histologically proven to be a leiomyosarcoma. Over 50 cases of leiomyosarcoma of the inferior vena cava have been reported in the literature, the majority of which occurred in women and 1/3 of which were associated with the Budd-Chiari syndrome. Histologically up to two mitotic figures per 10 high power fields have been scored. This case indicates the unreliability of a low mitotic index as an indicator of benign behavior of smooth muscle neoplasms of the venous system.
