Recently, a new set of criteria for its diagnosis has been suggested.1-3 Based on these criteria, to be considered a patient with AD an individual must have an itchy skin condition (or parental report of scratching or rubbing in a child) plus 3 or more of the following: (1) a history of flexural involvement (including cheeks in children younger than 10 years); (2) a personal history of asthma or hay fever (or a history of atopic disease in a first-degree relative of children younger than 4 years); (3) a history of generalized dry skin in the past year; (4) visible flexural eczema (including the cheeks and forehead and outer limbs in children younger than 4 years); and (5) onset of rash at younger than 2 years (not used if child is younger than 4 years).3
