Giant Multilocular Prostatic Cystadenoma in a 14-Year-Old Male: A Case Report of a Pediatric Pelvic Mass

Giant multilocular prostatic cystadenoma (GMC) is an extremely rare, benign tumor seen in both adult and pediatric males. The neoplasm originates from prostatic tissue and is typically found within the rectovesical pouch, varying in both size and morphology. Microscopically, GMC contains both glandular and cystic prostatic tissue lined by cuboidal and columnar epithelium. Symptoms often arise once the pelvic mass begins to obstruct the surrounding structures and organs, although invasion into surrounding tissue is unlikely. Common symptoms include abdominal pain, urinary retention, and dysuria. The standard treatment for GMC is surgical removal of the mass with good outcomes and only 1 known case of recurrence. Here we present the case of a 14-year-old male with GMC—the youngest patient reported to date—who presented with abdominal pain, difficulty voiding, and hydroureteronephrosis.

Prostatic tissue: an unexpected finding in a mature ovarian teratoma

Purpose Prostatic tissue in an ovarian teratoma is an unusual finding, whose initiation in a 46, XX karyotype tissue is yet to be clarified. We present a case from our files and review the literature for this intriguing finding. Methods Unstained histology sections of the ovarian teratoma containing prostatic tissue were evaluated using immunohistochemistry for PSA and androgen receptor. Results Both PSA and androgen receptor immunostainings were positive in the prostatic tissue. From the literature review, it appears that most of the patients (74%) with similar findings were either pregnant or experiencing a miscarriage, menopausal or infertile at presentation, showing that an imbalanced hormone status is frequently associated with the presence of male structures in ovarian teratomas.

Ectopic prostatic tissue presenting as a urinary bladder polyp in a young male

Ectopic prostatic polyps are uncommon lesions, sometimes found in the lower urinary tract, particularly the posterior urethra. Ectopic prostatic tissue in the bladder is very uncommon. Until now, only 43 cases of this lesion have been reported in the English literature. Clinically and endoscopically these lesions are often mistaken for malignancy. We report a case of ectopic prostatic tissue at the bladder neck in a young male. Histopathology and immunohistochemistry confirmed the prostatic nature of the tissue. Since the entity is benign and unlikely to recur, we emphasize that urologists and pathologists need to be familiar with this to avoid misdiagnosis and unnecessary overtreatment.

Ectopic Prostate Tissue Presenting as Urinary Bladder Tumor: The Imitation Game!

Ectopic prostate tissue is a rare phenomenon. Histologically and immunohistochemically it is indistinguishable from normal prostatic tissue but it is difficult to recognize and may be confused with malignancy when presenting as ectopic lesion in the urinary system. Therefore, awareness of this entity is essential for both urologists and pathologists to prevent misdiagnosis.
