Renal vein leiomyosarcoma: a case report

Renal vein is a strange location for primary vein leiomyosarcoma to be originated from, having been reported only thirty-three cases in the worldwide literature. Another case in a 74-years-old male, who presented intermittent left renal fosa pain, is reported here. Computed Tomography showed a left para-renal low-density solid mass near left kidney hilum arising from its renal vein. Radical nephrectomy and en-bloc tumoral excision were performed. Histopathological study of the specimen revealed a primary renal vein leiomyosarcoma. Neither chemotherapy nor radiotherapy was used on this patient. After a 72 months follow-up there was no signal of local recurrence of the disease or metastases, although the size of the tumor was > 3 cm and moderate-high mitotic activity was assessed. After literature review we conclude that long-term survival can be achieved after free-margin tumor resection.
