[What's new in dermatological therapy?].

The medical literature was reviewed to identify new dermatological therapies that appeared between October 2008 and October 2009. Randomized studies, cohort studies, meta-analyses were given priority. However, nonrandomized studies as well as clinical case studies were retained if they presented original findings. Fifty-four articles were selected on the following diseases : psoriasis, pemphigoid, pemphigus, hidradenitis, lichen, progressive systematic sclerosis, lupus, atopic dermatitis, urticaria, sexually transmitted diseases, warts, molluscum contagiosum, actinic keratoses, acne.
