[A case of renal cell carcinoma with solitary metastasis to the contralateral adrenal gland].

A 62-year-old female was admitted to our hospital with left flank pain and weight loss. Computerized tomography revealed a large left adrenal tumor and a small right renal tumor. A left adrenalectomy was performed initially to confirm sparing the left kidney. The left adrenal tumor weighed 650 g and was renal cell carcinoma histologically, suggesting a contralateral metastasis of the right renal tumor. Two months after the adrenalectomy, the right kidney was excised. The right adrenal gland was preserved. Pathologically, the renal tumor was also renal cell carcinoma. The patient has remained well for 34 months after the operation. The literature concerning the adrenal metastasis of renal cell carcinoma is briefly reviewed.
