[Bilateral adrenal metastases from renal cell carcinoma: a case report].

We report a case of renal cell carcinoma with bilateral adrenal metastases. A 57-year-old man was admitted to our hospital for a left renal mass. Computerized tomography and magnetic resonance imaging revealed a 4.5 cm left renal tumor and bilateral adrenal masses (3.0 cm on the right side and 2.0 cm on the left). A left nephrectomy and bilateral adrenalectomies were performed. The pathological findings showed clear cell carcinoma, G2 of left kidney metastasizing to both adrenal glands. The patient was administered supplementary hydrocortisone and was well 8 months after the nephrectomy and adrenalectomies without evidence of recurrence. Bilateral adrenal metastases from renal cell carcinoma are relatively rare. Our case seems to be the thirteenth case in the Japanese literature.
