[Uncertainty of practitioners between rational and evidence-based dermatology].

In opposition to intuitive and empirical approaches, rigorous medicine relies on two axes of development. Evidence-Based Medicine is currently put forward. However, it can not replace rational medicine rooted in physiopathological explanations. Dermatology does not escape such conceptual duality. Dermatopathology is one major pillar of rational dermatology. Such situation is jeopardized by health planners who deny the perennial skill of dermatologists and concede hegemony of dermatopathology to general pathologists.
