[Prostatic melanosis].
We report a case of prostatic melanosis in a 68-year-old patient. Although uncommon, some authors have reported an incidence of 4-10% for benign pigmented lesions of the prostate. It is important to distinguish this from the blue nevus where melanin deposits only involve the prostatic stroma. We discuss the theories explaining the origin of melanin in the prostate and its presence in the epithelium. The gross and microscopic findings of these conditions are described.
