[Metacronous transitional cell carcinoma of the prostatic urethra in a patient with history of nephroureterectomy for upper urinary tract urothelial tumor].

OBJECTIVES

We report one case of Metacronous transitional cell carcinoma (TCC) of the prostatic urethra in a patient with history of left nephroureterectomy 22 years before for urothelial neoplasia of the upper urinary tract.

METHODS

We describe the case of a 56-year-old male patient who presents with oligosymptomatic hematuria for several months. Cystourethroscopy showed irregular hyperemic lesions in the prostatic urethra, cold biopsy of which showed urothelial atypia. Pathology report of fragments of a posterior transurethral resection (TUR) was compatible with high-grade superficial transitional cell neoplasia. Instillation of Bacillus Calmette-Guerin (BCG) was indicated. Reevaluation TUR was performed.

RESULTS

Pathologic report of new samples showed TCC infiltrating the prostatic stroma. The extension study showed ilioobturator adenopathies. Chemotherapy did not achieve significant results. Radical surgery was rejected.

CONCLUSIONS

We emphasize the notable metachronous character of the transitional cell carcinoma of the prostatic urethra with respect to the upper urinary tract TCC. We also point out the metastasic capacity of these neoplasias, as well as the bad prognosis of those cases in which chemotherapy is not effective.
