Abstract

Primary malignant melanoma of the urinary bladder is a rare lesion. We report the case of a 78-year-old male with no previous history of cutaneous melanoma who presented with hematuria. Further investigation with imaging and cystoscopy raised suspicion of a primary bladder and ureteric melanoma, which had subsequently metastasized. This was confirmed with histological assessment and a thorough search for alternative primary lesions. Unfortunately, our patient passed away prior to receiving any oncological treatment for his metastatic melanoma, underscoring both the high mortality of this lesionandtheneedforaconsensusondefnitivetreatment.
