Quoi de neuf en dermatologie clinique ?

The actuality in clinical dermatology is, to our opinion, dominated by the emergent or reemergent infections (arboviruses, poxviruses, mycobacteria, leishmania, staphylococcus, papillomaviruses, bedbugs…) and their involvement in certain diseases (atopia, psoriasis), tumours or syndromes with dermatologic signs (IRIS). The cutaneous adverse side effects of the targeted chemotherapies and biotherapies are consequently better surrounded. Some rare new anatomoclinical entities are identified but «classics» (Lipschütz ulcer, pityriasis rosea, deep dissecting hematoma, puffy hand syndrome, disseminata alopecia areata) are rediscovered and better represented thanks to help, sometimes, by new techniques.
