Classifying skin diseases: Until where should we go?

New molecular mapping techniques appear to allow clinicians to design treatments in some cases of resisting cancers. Such sensitive analysis were already able to depict molecular pathways of several inflammatory skin diseases. An accompanying article by Garzorz-Stark et al. show how these tools could improve the classification of skin inflammatory diseases now based on clinical and pathological features. At last, the final aim of these tools is to predict treatment response in a patient. The utility of "precision" or personalized medicine in cutaneous inflammatory diseases could join the furrow drawn in cancer.
