Facies: the value of an old diagnostic tip in pediatric dermatology.

The authors examine what is meant as facies in medicine. After an introduction to the word's understanding, they move on listing some dermatological conditions associated to peculiar facies in the child. Starting from atopic dermatitis, the authors develop an algorithm including Genodermatoses, Neurocutaneous Disorders, and Multiple Congenital Anomalies Syndromes. They emphasize the distinctive features of the lesions on the face and their fundamental diagnostic importance.
