[Prostatic carcinoma with bilateral testicular metastasis: a case report].

A 77-year-old man was referred for the treatment of urolithiasis. The patient noticed the swelling of bilateral scrotal contents 2 weeks previously and had been suffering from bladder symptoms for several years, dysuria and pollakisuria. Therefore, he was admitted for the treatment of stones and further examination. By transrectal examination, prostatic carcinoma was suspected. Biopsy of the prostate and bilateral orchiectomy revealed the prostatic carcinoma and the metastatic adenocarcinoma of the bilateral testis. The histological or immunohistological examination indicated that the metastatic adenocarcinoma was prostate in origin.
