AbstractLeiomyosarcoma of inferior vena cava is a rare malignant mesenchymal tumor of the venous system that typically occurs in adulthood. Correct and early recognition of leiomyosarcoma is very important, because a complete resection of the tumor (with occasionally chemio-or radiotherapy) can lead to prolonged survival. We report a case of a 54-year-old man suffering from the leiomyosarcoma of inferior vena cava with infiltration of retroperitoneum and right adrenal gland.
