Urinary bladder metastasis from malignant melanoma.

Bladder metastases from malignant melanoma are very rare, with only about 30 cases reported to date. They are often associated with synchronous metastases elsewhere in the body and portend poor prognosis. Herein, we present the case of a 62-year-old man with a history of two completely resected, non-node-metastatic cutaneous malignant melanomas who presented with gross haematuria as his only symptom. We then proceed to discuss the diagnostic process and prognostic implications of primary and metastatic malignant melanomas of the urinary bladder. Level of evidence: 5 [ABSTRACT FROM AUTHOR]
