title: [Melanosis of the urinary bladder].
abstract: Melanosis of the bladder is rare. Only 10 cases have been described in the literature. We present the case of an 80-year-old woman with neurogenic lower urinary tract dysfunction due to spinal paralysis. During the diagnostic work-up which included cystoscopy, black spots in the bladder wall were observed. Histopathological evaluation revealed a benign suburothelial melanosis. Thus, with cystoscopic suspicion of a malignancy (melanoma), a biopsy is mandatory and regular cystoscopic follow-up is recommended.
