Wöllner J Janzen J Pannek J 2016 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. https://sonar.ch/global/documents/189714 eng info:eu-repo/semantics/altIdentifier/doi/10.1007/s00120-015-3953-6 info:eu-repo/semantics/altIdentifier/pmid/26358438 Der Urologe.
