title: [Primary urothelial carcinoma with sarcomatous transformation of the prostate].
abstract: A 64-year-old man visited our hospital presenting with macroscopic hematuria. Right hydronephrosis and hypertrophy of the prostate were shown by DIP and MRI respectively. A small papillary tumor at the prostatic urethra was found by cystourethroscopy. Then, we performed transurethral resection of the tumor and trans-perineal needle biopsy of the prostate, and diagnosed him as primary urothelial carcinoma of the prostate. Following neo-adjuvant chemotherapy(MVAC), the patient was treated with radical cystoprostatectomy. The histopathological examination showed urothelial carcinoma with concomitant sarcomatous transformation. Six months after the surgery, he had a recurrence of the tumor in the pelvic cavity. He was treated with the second-line chemotherapy using paclitaxel and gemcitabin combined with the radiation therapy, resulting in the disappearance of the tumor. No evidence of the recurrence has been observed for 3 years.
