Giant Botryoid Fibroepithelial Polyp of the Bladder in a 6-Year-Old Girl
Main Article Content
Abstract
Fibroepithelial polyps (FEPs) of the urinary tract are a rare benign tumour in the bladder. It arises from mesoderm and is mostly found in the ureter and ureteropelvic region. The authors report a case of a six-year-old girl with no history of urogenital abnormality who presented with haematuria and suprapubic pain. Ultrasound and computed tomography showed a large multilobulated mass in the urinary bladder. The resected specimen exhibited a bulbous mass with a botryoid surface. Microscopically, the polypoidal lesion is covered by reactive transitional epithelium with the presence of cystitis cystica et glandularis with scattered spindle cells; fibroblast and smooth muscle cells. By excluding all the differential diagnoses according to histomorphology and immunostain findings, diagnosis of Giant Botyroid FEP is made. This paper also discussed the differential diagnosis for FEP.
