[A case of transitional cell carcinoma of the prostate]

A 46-year-old man was admitted to our hospital with the complaint of gross hematuria and renal failure. The patient had undergone right nephrectomy 10 years earlier suffering from nephrotuberculosis, and the remaining left side manifested severe hydronephrosis and vesicoureteral reflux (VUR). After the immediate nephrostomy, renal function was recovered and hematuria was improved preservatively. By the rectal examination, a goose egg size and stony hard prostate was detected. The needle biopsy of the prostate revealed pathologically transitional cell carcinoma (TCC) G2, and the image findings showed stage of T4N0M0 of the prostatic carcinoma. Modified pelvic exenteration was performed, and specimens were examined by the step section method. The diagnosis was TCC, G2 > G3 and stage of pT4N0 in the right lobe of the prostate. This case is she 20th reported case in Japan. We emphasize the importance of the mapping of dissected specimens and the reviewed literature.
