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.
Key Words: Heterotopic prostatic tissue; Retrovesical space
