Prostatic melanosis is a very rare, benign lesion characterized by the presence of melanin in the epithelium of the prostate gland and stromal dendritic cells, requiring no additional treatment. It constitutes the melanocytic lesions of the prostate together with blue nevus and malignant melanoma. We present a case with prostatic melanosis because it is rarely seen and its distinction from malignant melanoma is clinicopathologically very important.
