Metastatic melanoma to the kidney presenting with renal vein tumor thrombus.

We report on a patient with metastatic melanoma to the kidney who presented with a renal vein thrombus to the inferior vena cava. Three years after his initial lesion of the scalp, a 34-year-old Egyptian man was found to have two brain metastases and an 11-cm left renal metastasis with a tumor thrombus in the renal vein. After resection of the brain metastases, with no evidence of additional metastases, the patient underwent left radical nephrectomy and tumor venous thrombectomy. The patient later had tumor recurrence at multiple sites. He did not respond to systemic treatment and died 5 months later.
