Abstract
A study has been made of 76 cases of metastatic melanoma presenting over a ten year period. Of this group. 64.5 per cent developed clinical metastases within 12 months of presentation with the primary disease while 80 per cent had developed metastases by three years. Fifty per cent of our patients had ulcerated lesions, and most patients had thick lesions on histological examination. The site of the first metastasis occurred In the regional lymph nodes In 65 per cent and in viscera In 22 per cent. Subsequent clinical metastases were widespread and their distribution Is recorded. Of those patients with nodal Involvement, 75 per cent had only one node involved on histological examination. Only 14 of the 76 patients are alive and of these nine are alive without disease. The surviving patients had regional node, intransit or local metastases present. Disease beyond these areas was fatal. We have recorded the therapeutic modalities used without attempting to study them objectively.
