[Primary leiomyosarcoma of the liver]. / Leiomiosarcoma primario de hígado.

We report a case of primary hepatic leiomyosarcoma in a 70 years old woman presenting with hepatomegaly, right upper quadrant pain and impairement of general status. A left hemihepatectomy was undertaken revealing a single tumor of 7 cm in diameter in the left hepatic lobe. An immunohistochemycal study was performed indicating the smooth muscle nature of the tumor. The patient died 6 months later without evidence of active tumoral disease. This is the 28th report on primary leiomyosarcoma of the liver in the world literature.
