[Misdiagnosis of a Leiomyosarcoma of the inferior vena cava as a renal cell carcinoma]

[Leiomyosarcoma of the inferior vena cava. Review of a rare disease]

Primary sarcomas of the great vessels are rare. Their most common site is the inferior vena cava. We report a primary leiomyosarcoma of a 41 year old female patient localised just below the right renal vein. The resected tumour showed the histological signs of a well differentiated, progesterone positive leiomyosarcoma. The case is discussed on the data of the reviewed literature.
