title: Diagnosis of retrovesical ectopic and hyperplastic prostate tissue by transrectal needle biopsy.
abstract: We report on an ectopic prostate in a 50-year-old man. Transabdominal ultrasonography, pelvic computed tomography, and pelvic magnetic resonance imaging revealed a heterogeneous tumor 8 cm in diameter in contact with the posterior wall of the urinary bladder. The tumor was histologically confirmed to be a benign prostatic hyperplasia. This is the 3rd case of retrovesical ectopic prostatic tissue which was diagnosed by transrectal needle biopsy.
