Abstract
in English, German

Melanosis of the urinary bladder is an extremely rare benign condition in which melanin deposits occur in the urothelial and stromal cells. We report such a case in which melanosis of the urinary bladder was detected in a 55-year-old woman with known multiple sclerosis during an extended workup due to urinary urgency complaints. The findings were confirmed by biopsy.

Die Melanose der Harnblase ist eine äußerst seltene, gutartige Erscheinung, bei der es zu Melaninablagerungen in den Urothel- und Stromazellen kommt. Wir berichten über einen solchen Fall, bei dem im Rahmen einer erweiterten Abklärung aufgrund einer Drangsymptomatik bei einer 55-jährigen Patientin mit bekannter multipler Sklerose eine Melanose der Harnblase festgestellt wurde. Der Befund wurde mittels einer Biopsie bestätigt.

Keywords: Bladder; Cystoscopy; Melanosis; Neurogenic voiding dysfunction; Urgency.
