Rhabdomyoma of prostate

An asymptomatic nineteen-year-old white man presented with a markedly enlarged and indurated prostate. Urologic evaluation including cystoscopy, prostatic ultrasound, pelvic computerized tomography (CT) scan, and pelvic nuclear magnetic resonance imaging revealed a prostatic mass impinging on the bladder. Transrectal biopsies returned the pathologic diagnosis of rhabdomyomatous hamartoma. We report the first case in the English literature of extracardiac rhabdomyoma found in the male genitourinary tract.
