A case of inverted papilloma of the posterior urethra is reported. A 59-year-old male was admitted with the chief complaint of difficulty in urination. Cystourethroscopy revealed a polypoid tumor with a smooth surface on the stalk arising from the prostatic urethra, concomitant with prostatic hypertrophy. Transurethral resection of the tumor and the prostate was performed. No evidence of recurrence has been noted in the 9 months after surgery. This is the 26 th case of inverted papilloma of the posterior urethra reported in Japan.
