Abstract: Chromophobe renal cell carcinoma (ChRCC) metastatic to the testis has not, to the best of our knowledge, been reported in the literature. Nor have there been reports of delayed bilateral adrenal metastasis of ChRCC. Here we report a case of metachronous contralateral testicular and bilateral adrenal metastasis of ChRCC in a 70-year-old man who underwent right radical nephrectomy for RCC six years ago. He was admitted to the hospital because of left intrascrotal enlargement of two-month duration. Ultrasonography revealed a mass in the upper pole of the left testis. Computed tomography (CT) showed irregular masses in the bilateral adrenal area. Left radical orchiectomy and laparoscopic bilateral adrenalectomy were performed. The pathologic examination showed metastatic ChRCC in the left testis and bilateral adrenal gland. Postoperative follow-up showed that the patient had survived for at least 56 months without recurrence. The case highlights the unique behavior of RCC with an unusual site of metastasis and favorable survival after multiple metastasectomy.

Key words: Renal cell carcinoma (RCC), Testicular metastasis, Adrenal metastasis, Metastasectomy
