A 74-year-old woman presented to the urology clinic with a protruding mass in her urinary bladder detected by ultrasonography. She had no symptoms. Cystoscopy revealed a 1-cm lesion with a lock of 1-cm-long white hair-like structures on the right side of the bladder. White plaques were also noted covering some areas of the bladder. Transurethral resection of the lesion and biopsy of the white plaques were performed. Pathological examination confirmed a diagnosis of keratinizing squamous metaplasia of the bladder with no evidence of malignancy.
