The prognosis of MM is related to a number of factors including sex, tumour site and ulceration, but the single most important guide to prognosis is the Breslow thickness.6 This is a measure of the depth of invasion of the tumour from the granular layer of the epidermis. Lesions that are confined to the epidermis have no metastatic potential. Those that are less than 1 mm in depth have a very good prognosis, with 5-year survival rates of approximately 95%. Tumours deeper than 4 mm are associated with survival rates of about 50%. The involvement of regional lymph nodes with metastases at presentation further reduces survival rates to 25-50%.7
