Melanoma metastasis to the bladder: A case report of an underdiagnosed entity.

INTRODUCTION: Melanoma is an aggressive form of skin cancer known for its significant risk of metastasis. Metastasis to the urinary bladder is rare. CASE PRESENTATION: We report a case of a 75-year-old woman with melanoma metastasis to the bladder treated with transurethral resection of the bladder tumor, confirmed by immunohistochemistry. DISCUSSION: Cystoscopy is essential for all melanoma patients presenting with urinary symptoms. Treatment necessitates a multidisciplinary approach. CONCLUSION: Despite advancements, the prognosis remains guarded, underscoring the need for further research to enhance therapeutic strategies.
