  • Urothelial melanosis is a rare finding characterized by abnormal pigmentation noted on cystoscopic evaluation and histologically defined by melanin deposition in the urothelium. Although generally considered benign, few cases of urothelial melanosis have been reported in the literature and the risk of recurrence or progression remains largely unknown. Four cases associated with urothelial cell carcinoma have been previously described. Here, we report a case of urothelial melanosis and review previously published cases in the literature.
