Melanosis of the Bladder: A Case Report and Review of the Literature

Melanosis of the bladder is a pathology defined as intracytoplasmic brown-black pigment deposit in urothelial cells without cytological atypia. A 69-year-old man case showed melanic pigment in the bladder wall through specific immunochemistry. Melanosis of the bladder’s real prevalence and malignant potential are hard to define, due to its prevalence among asymptomatic adults hasn’t been described by this moment, and follow-up though periodic Urethrocystoscopy would be necessary in order to clarify its malignant potential.
