Ectopic prostate tissue at the bladder dome.
A 71-year-old white man with asymptomatic microscopic hematuria had a sessile tumor at the dome of the bladder containing benign prostatic glandular tissue. Benign prostatic polyps occur commonly in the prostatic urethra and bladder neck as vestigial remains of embryonic prostatic elements. Ectopic prostatic tissue elsewhere is rare and has not been described previously arising at the bladder dome. The origin of prostate glands in this unlikely location is unclear. The clinical course of ectopic prostatic polyps at any location is benign, although local recurrence has been reported.
