Primary Bladder Neurofibroma: A Rare Case with Clinical Implications and Diagnostic Challenges.

Neurofibroma of the genito-urinary tract is rare. Urinary bladder is the commonest organ involved in cases of urinary tract involvement. Patients present early in life and there is male preponderance. We discuss here a case of primary neurofibroma of the urinary bladder in a 52-year-male presenting with haematuria, irritative bladder symptoms and pelvic mass. Cystoscopy showed a swelling in the left lateral wall. A transurethral biopsy revealed neurofibroma of the urinary bladder. Immunohistochemical studies confirmed the diagnosis.
