The classification of melanoma: time for a further revision?

The current classification of cutaneous melanoma was developed in 1972 and revised in 1982. Since that time new concepts and terminology have evolved that require consideration of a further revision. This paper reviews some of the concepts that will form part of that process. Regional meetings of interested parties have been held to review the classification and there will be an open meeting on the topic at the 1997, 4th World Conference on Melanoma in Sydney, Australia. A questionnaire is included that will allow the interested reader to provide comments on the topic.
