[Leiomyosarcoma of the inferior vena cava].

Leiomyosarcoma of vena cava are rare tumors. They occur preferentially in the inferior vena cava. They affect preferentially women and the median age of incidence is on fifth decade. Their prognosis depends on the severity of venal occlusion, local invasion and presence of metastases. We report the case of a woman who died from occlusion of the inferior vena cava. We review the literature.
