title: [Prostatic metastasis of renal cell carcinoma].
abstract: A 71-year-old man underwent a radical nephrectomy for right renal cell carcinoma in April, 2005. Pathological findings revealed clear cell carcinoma, G3＞G2, pT3a. Three years later, he underwent a craniotomy for tumor resection of solitary brain metastasis. In October, 2008, he came to our hospital because of urinary retention. Benign prostate hypertrophy was diagnosed by ultrasonography and digital rectal examination. Serum prostate specific antigen level was 2.55 ng/dl. While he was treated with oral α 1-blocker initially, a urethral catheter was inserted in December, 2009. Because of frequent obstruction of the catheter by hematuria, transureathral prostectomy was performed. Pathological findings revealed prostatic metastasis of renal cell carcinoma. Metastasis of renal cell carcinoma to the prostate is rare, and only 7 cases including the present case have been reported.
