Benign fibroepithelial bladder polyp: a rare cause of childhood haematuria

Abstract

Haematuria in paediatric population is common yet alarming. It warrants a thorough physical examination and other investigations. Of late, a number of extremely rare aetiology of childhood haematuria have come to forefront. One such uncommon cause is benign fibroepithelial urinary bladder polyp. The presentation is of a child with intermittent haematuria exacerbated by physical/sports activity associated with or without suprapubic pain. Diagnosis is usually made by ultrasonography and cystoscopy and confirmed by histopathological examination. Treatment is surgical and involves cystoscopic transurethral resection of the mass. The exact aetiology of benign fibroepithelial polyp is uncertain with no clear guidelines on long-term surveillance. However, these cases should be subjected to cystourethroscopy if haematuria recurs. Treatment is surgical with good long-term prognosis. Not much is written in literature about benign fibroepithelial bladder polyp.

Fibroepithelial Polyp: An Unusual Cause of Acute Urinary Retention in a 5-Year-Old Boy

“…The differential diagnosis of an anatomic mass at the bladder base causing dramatic urinary obstruction and retention in a previously healthy child includes hemangioma, leiomyoma, benign bladder polyp, urethral cyst or polyp, rhabdomyosarcoma, neurofibroma, urinary bladder cystitis cystica, ureterocele, posterior urethral valves, persistent müllerian remnant, transitional cell carcinoma, and adenocarcinoma. [1][2][3][4][5][6] In our patient's case, in addition to the transurethral cystoscopic surgical findings, the histopathologic report of fibrovascular and muscular tissue with focally preserved urothelial lining and foci of granulation tissue was compatible with a diagnosis of benign fibroepithelial polyp (FEP) of the bladder base.…”

“…FEPs affecting the bladder and/or urethra are quite rare. [2][3][4][5][6][7] Histologically, FEPs of the genitourinary system are composed of a core of fibrovascular tissue lined by benign urothelium. 2,4 They are usually solitary, as seen in this patient's case, but cases of multiple isolated polyps have been reported.…”

Bladder mulberry-like fibroepithelial polyp with calcification and squamous cell metaplasia mimicking bladder carcinoma: case report and literature review

“…Fibroepithelial polyps (FEPs) of the bladder are a rare, benign disease, which most commonly occurs in the ureter 1 and is extremely rare in the urinary bladder. [2][3][4][5][6][7] There have only been seven cases of bladder FEPs published in the English literature over recent decades. 4,[6][7][8][9][10][11] This lesion is usually discovered in children, and it has rarely been reported in adults.…”
