Ectopic prostatic adenoma in retrovesical space

Abstract

In 1912 Lowsley described that the neonatal prostate consisted of 7 lobes, that is anterior, posterior, right lateral, left lateral, median, subcervical and subtrigonal. Prostatic tissue outside of the 7 lobes was described as ectopic and most of those cases reported were so-called prostatic polyps. Ectopic prostatic tissue in the bladder also has been reported. However, there have been few reports of ectopic prostatic tissue outside of the urinary tract. We report a case of an ectopic prostatic adenoma in the retrovesical space.
