title: Granular cell tumour of the urinary bladder: a case report and review of the literature.
abstract: Granular cell tumor of the urinary bladder is an exceedingly rare disease, with only 10 cases reported so far in literature. We report a case of granular cell neoplasm of the bladder incidentally found in a 44-year-old woman during an abdominal ultrasound examination for evaluation of stress urinary incontinence. The patient underwent a transurethral resection of the mass and histological examination revealed the presence of a granular cell tumor. Immunohistochemical staining for neuron-specific enolase and S100 protein was positive. At a 6-month follow-up the patient is free of bladder recurrence.
