Today, 20 years after Clark and Elder postulated their tumor progression model of melanocytic lesions from common nevi to melanoma, there are still controversies surrounding this subject. Despite modern molecular biological developments, a consensus about the question, if thedysplastic nevus should be considered as a separate entity, melanoma precursor or just represent a diagnostic dilemma, still seems to be impossible. In addition, since the term melanocytic dysplasia is not precisely defined with regard to all diagnostic methods (clinical morphology, dermatoscopy, dermatopathology, molecular biology), there is considerable confusion. The question remains if a quite arbitrary classification of melanocytic lesions such as dysplastic nevus is useful at all. In daily practice, dermatologists should be aware of the fact that each suspicious melanocytic lesion could represent an early malignant neoplasia, regardless whether it is formally named dysplastic nevus or initial malignant melanoma. We conclude that solid dermatological experience plus novel tools of documentation represent the key factor to minimize patients' risk.
