[Inflammatory pseudotumor of the urinary bladder: a case report]

Abstract

A 52-year-old man presented with gross hematuria. He had neither history of urinary tract infection nor trauma. Cystoscopy revealed a bladder tumor with ulcer on a left lateral wall. Computed tomography confirmed a round solid mass 3 cm in diameter invading deeply into the muscle layer of the urinary bladder. Transurethral biopsy revealed an inflammatory pseudotumor of the urinary bladder. Partial cystectomy was performed. This is the 38th reported case of inflammatory pseudotumor of the urinary bladder in Japan. No local recurrence was seen 3 months after surgery.
