Fibroepithelial polyp of the prostatic urethra in an adolescent
Section snippets
Case report
A 16-year-old adolescent presented to the urology service in urinary retention after 4 months of voiding difficulties. A CT scan of the pelvis with contrast revealed an irregular lobulated and nonenhancing mass, which appeared to arise from the prostate and extended into the bladder base near the ureteral orifice. The radiological impression was that the lesion was worrisome for rhabdomyosarcoma.
Cystocopy detected a 2.0-cm-diameter polypoid mass at the right bladder neck and proximal urethra
Pathologic findings
The specimen received in the fresh state consisted of a roughly polypoid/ovoid fragment of tan soft tissue which, on sectioning, revealed a central pale area and associated surface papillary fronds. It measured 1.5 × 1.4 × 0.3 cm. Separately received was an irregular fragment of pink-tan soft tissue measuring 0.3 × 0.2 × 0.1 cm, designated to be the prostatic urethral mass stalk.
Microscopically, the polypoid lesion consisted of edematous papillary fronds with relatively hypocellullar
Discussion
Fibroepithelial polyp of the prostatic urethra is a benign and rare congenital lesion [1], [2].
It is seen in the pediatric population more common in males than females and has been rarely reported in adults [3], [4]. Because of its location, it may cause a diversity of urinary symptoms including hematuria, dysuria, urinary tract infections, and obstruction, which may result in urinary retention [1], [3]. Imaging and endoscopic procedures usually detect the presence of an obstructing, sometimes

2014, African Journal of UrologyCitation Excerpt :Most patients present with hematuria and obstructive urinary symptoms: dysuria, acute urinary retention, post void dribbling and urinary hesitancy. Other modes of presentation are recurrent urinary infection and painful interlabial mass in girls due to the prolapsing of a pedunculated polyp out of the external urethral meatus [3]. Most of lower tract urothelial polyps arise from posterior urethra.

2013, Urologic Oncology: Seminars and Original InvestigationsCitation Excerpt :Rhabdomyosarcoma is discussed in detail in a later section. The biologic behavior of fibroepithelial polyp is uniformly benign, although 1 study identified translocation of chromosomes 4 and 6 in a single case, raising the question of whether such lesions represent a benign neoplasm or whether a constitutional abnormality was present in the particular case [37]. Urothelial papilloma is a benign, polypoid urothelial neoplasm.

2012, Journal of Equine Veterinary ScienceCitation Excerpt :In men, prostatic cystadenomas are rare, benign, locally expansive, remain retroperitoneal, and tend to reoccur if not completely excised [9,10]. Although there are reports of intraurethral cysts of prostatic origin [11-13] and congenital fibroepithelial polyps of the prostatic urethra in infants and young males [14], human prostatic cystadenomas reportedly do not protrude into the urethral lumen. In contrast, the cystadenoma in horse 1 had an intraurethral component that had progressed into the urethra by growth through the prostatic ducts.
