Abstract
-
Heterotopic prostatic tissue has been reported in a variety of sites within and outside
the urinary tract. Extra-urethral ectopic prostatic tissue is a distinct entity and may be more
common than previously thought. We report a case of heterotopic prostatic tissue in
71-year-old man. Pelvic CT scan showed a well circumscribed cystic mass in the
retrovesical space. Grossly, the tumor was 7.5 7.0 2.8 cm and revealed an ovoid unilocular
cyst containing grayish amorphous granular materials. The prostatic origin of the tissue was
confirmed by immunohistochemical staining for prostate specific antigen.
