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.
