[What's new in clinical dermatology?].

Medical articles published between September 2011 and September 2012 were selected based on themes related to clinical dermatology. Therapeutics, pediatrics, oncology, sexually transmitted diseases, and major system diseases such as sarcoidosis and connective tissue disease were not retained. The subjects reviewed were: (i) epidemiology, particularly the risks of exposure to infectious agents; (ii) diagnostic tools, dominated by dermoscopy and teledermatology; (iii) the description of new disorders and the reassessment of older diseases; (iv) complementary tests in certain types of dermatosis; (v) a few large "works in progress" in dermatology, where clinical aspects and biological research intertwine and contribute one to the other.
