Renal vein leiomyosarcoma.
The third reported case of renal vein leiomyosarcoma is presented. Diagnosis was not made until exploratory celiotomy revealed a tumor originating from the left renal vein. The tumor was resected with margins of normal vein, and the patient was alive without recurrence 12 months after operation. Review of 65 cases of leiomyosarcoma originating in other retroperitoneal structures revealed a two-year survival rate of 20%. Therefore, we recommend consideration of postoperative adjunctive chemotherapy for renal vein leiomyosarcomas.
