Malignant melanoma is a common cancer in young people and its incidence is rising in the UK. The management of the disease is evolving, with new approaches to the treatment of locally advanced and systemic disease in particular being rapidly developed. Sentinel node biopsy is a valuable treatment option for the staging of melanoma, and completion lymphadenectomy in node-positive patients improves local disease control. However, early clearance of occult microscopic nodal disease has not been proven to confer a melanoma-specific survival advantage. Delays in the diagnosis and treatment of melanoma lead to claims being brought in negligence, but establishing causation in such cases can be difficult.
