Granular Cell Tumors of the Urinary Bladder: An Extremely Rare Entity and Literature Review

Granular cell tumors (GCTs) of the urinary bladder are extremely rare tumors and there are only 26 reported cases in the literature. GCTs are usually benign tumors and it is important to differentiate them from other neoplasms of the bladder such as carcinomas. We herein report a case of a benign GCT of the urinary bladder.

Mesanenin Granüler Hücreli Tümörü: Oldukça Nadir Bir Olgu ve Literatür Derlemesi

Mesanenin granüler hücreli tümörleri (GCT) oldukça nadir görülen tümörlerdir ve literatürde sadece 26 olgu bildirilmiştir. GCT’ler genellikle iyi huylu tümörler olmakla birlikte karsinomlar gibi mesanenin diğer neoplazmaları ile ayırıcı tanısını yapmak önemlidir. Biz burada idrar kesesinin iyi huylu bir granüler hücreli tümör olgusunu bildirmeyi amaçladık.
