[A case of renal cell carcinoma with contralateral adrenal metastasis].

A case of a 55-year-old man with renal cell carcinoma metastasized to the contralateral adrenal gland is reported. He was admitted to our hospital with the complaints of hematuria and weight-loss. CT and arteriography revealed left renal tumor and contralateral adrenal mass. We made the diagnosis of left renal cell carcinoma with right adrenal metastasis, and performed left total nephrectomy and right adrenalectomy. Histologically, the adrenal mass was clear cell carcinoma, and it was diagnosed as metastasis from the left renal cancer. We reviewed 9 cases of renal cell carcinoma metastasized to the contralateral adrenal gland in the Japanese literature and discussed the effectiveness of pre-operative CT evaluation.
