A 73-year-old man was referred to our hospital with macrohematuria. The serum level of the PSA ranged within normal limits. Urethroscopy revealed a papillary tumor near the verumontanum. The tumor was resected transurethrally. Histopathological examination revealed adenocarcinoma with papillary growth and the tumor displayed immunoreactivity for PSA stain. Radical prostatectomy was performed. The follow-up at 11 months revealed neither local recurrence nor distant metastases.
