J Int Med Res. 2020 Jan;48(1):300060519896911. doi: 10.1177/0300060519896911.

Abstract

Fibroepithelial polyps (FEPs) are a rare, benign disease in the urinary system. We present a clinical case of a 34-year-old woman with a symptomatic bladder tumor. Cystoscopy showed a mulberry-like mass with calcification in the bladder trigone. After transurethral resection, histopathology showed an FEP in the bladder with calcification and squamous cell metaplasia. The patient was discharged from hospital 3 days after surgery. We review the recent literature to summarize the clinical manifestations, treatments, and prognosis of bladder FEPs.

Keywords: Bladder; cystoscopy; fibroepithelial polyp; hematuria; squamous cell metaplasia; transurethral resection.
