Abstract We report an unusual case of retrovesical ectopic prostate tissue in a 73-year-old man with primary prostate cancer. The man’s prostate-specific antigen was 24.66 ng/ml.Transabdominal ultrasonography, pelvic computed tomography,and pelvic magnetic resonance imaging demonstrated a heterogeneous 8.5 × 8.0 × 7.0 cm mass in contact with the posterior wall of the urinary bladder. The patient underwent a retropubic radical prostatectomy and resection of tumor. Pathological examination of prostate revealed a prostatic adenocarcinoma, Gleason score of 4 + 5 = 9, and the retrovesical tumor was confirmed to be a benign prostate tissue.

Background Ectopic prostatic tissue is a relatively uncommon entity that is most commonly encountered in the lower male genitourinary tract [1]. However, only 10 cases of ectopic prostatic tissue situated in the retrovesical space have been published up to date [2-4]. Here, we report an unusual case of retrovesical benign ectopic prostatic tissue accompanied by primary prostate cancer. Case report A 73-year-old man suffering from progressive dysuria was admitted to the urology department of our hospital. His medical, personal, and family histories were unremarkable. Transabdominal ultrasonography confirmed a heterogeneous tumor with solid and cystic lesions in contact with the posterior wall of the urinary bladder, while urography showed a normal upper urinary tract. Pelvic computed tomography demonstrated a heterogeneous contrast-enhanced mass about 8.0 cm in diameter in the retrovesical space (Figure 1). Pelvic magnetic resonance imaging showed a tumor of heterogeneous intensity with a multilocular cystic structure (Figure 1). The level of the prostate-specific antigen (PSA) showed an elevation (24.66 ng/ml). It was not clear where the retrovesical tumor originated from.

biopsy was subsequently performed, which failed to get the retrovesical tumor but revealed a primary prostatic adenocarcinoma, with Gleason score of 4 + 3 = 7. Following discussion of therapeutic options, the patient underwent a retropubic radical prostatectomy and resection of tumor. The resected tumor was elliptical with complete capsule and measured 8.5 × 8.0 × 7.0 cm in size. At pathological examination, the mass was confirmed to be benign prostatic tissue (Figure 2). Histological diagnosis of the prostate suggested prostate adenocarcinoma, Gleason score of 4 + 5 = 9, involving both sides of the gland (Figure 2). There was no evidence of ly
