Isolated schwannoma of the urinary bladder: a case report and review of the literature

Abstract

The urinary bladder schwannoma is an extremely rare primary urologic tumor. Schwannoma arises from the Schwann´s cells in the nerve sheaths and is almost associated with von Recklinghausen´s disease. We report a case of schwannoma in a 35-year old female who presented with urinary frequency for 2 months with absence of evidence of von Recklinghausen disease and successfully treated with transurethral resection of bladder lesion (TUR_B). To the best of our knowledge, this represents only the 10th case of benign schwannoma of the urinary bladder in a patient without von Recklinghausen disease. We report a case of an isolated schwannoma of the urinary bladder, and also searched the English literature as we had access to bladder schwannoma.
