Leiomyosarcoma of the superior vena cava. A first case with resection

Leiomysarcomas, rare malignant tumors of the veins, are located predominantly in the inferior vena cava. We report our experience with a leiomyosarcoma in the superior vena cava of a 44-year-old white man. The lesion had been locally excised and then recurred 2 1/2 years later. The recurrent tumor was widely excised and the superior vena cava was repaired with a saphenous vein patch graft. The area of the recurrence was treated with cobalt 60 therapy. Four years later, 6 1/2 years after initial treatment, the patient is alive and well without evidence of recurrence.
