Leiomiosarcoma de la vena cava inferior. Presentación de un caso y revisión del cuadro clinicopatológico

We present a case of leiomyosarcoma of the inferior vena cava in a 63 year old man who subsequently died due to vena cava syndrome secondary to the tumour. Autopsy revealed the primary neoplasm, and immunohistochemistry confirmed the histological diagnosis. Morphology and differential diagnosis are discussed together with a review of the literature.
