Abstract

This assay examines critically the concept of 'dysplasia' as it applies to melanocytic neoplasia and concludes that the concept is flawed. Doubt is cast also upon the validity of the concepts of a dysplastic naevus and a dysplastic naevus syndrome. The author is of the view that most malignant melanomas arise de novo and not in pre-existing dysplastic naevi. Because so-called dysplastic naevi are considered by the author to be the commonest melanocytic naevi in man and devoid of nuclear atypia, he proposes that they be re-named 'common naevi' in the interest of simplicity, accuracy, and care of patients. Lastly, it is suggested that resolution of problems in the sphere of melanocytic neoplasia might be accomplished more readily were terms like dysplasia, dysplastic cells, dysplastic naevi, and the dysplastic naevus syndrome eschewed.
