[Primary pigmented malignant melanoma of the bladder treated with radical urethrocystectomy and adjuvant therapy].

Primary malignant melanoma of the urinary tract is a rare entity with less than 50 cases reported worldwide. The following case concerns a 64-year-old woman whom we first saw in our emergency room due to gross haematuria. As part of the subsequent diagnostic investigation, we detected a primary malignant melanoma of the bladder and the urethra. The patient was treated with radical urethrocystectomy including pelvic lymphadenectomy and an ileum conduit. This was followed by a year of adjuvant therapy using checkpoint inhibitors.
