[Atopic dermatitis of the adult: clinical presentation, complications and comorbidities].

Atopic dermatitis (DA) is a chronic inflammatory skin disease. Its incidence and prevalence is increasing, especially in industrialized countries. The prevalence of AD in adults is estimated at 1-3 % of the general population and can present as adult-onset AD, or as infantile/childhood AD that persists, or recurs in adulthood. There are no specific diagnostic criteria for adult AD. Diagnosis may be also complicated by the fact that the clinical manifestations sometimes differ from pediatric AD. Moreover, many recent studies have identified adult AD as a systemic disease. Due to its chronicity and comorbidities, Adult AD has a major impact on quality of life and working abilities of affected patients. With the emergence of new treatments, we should see more and more adult AD in the future, a better knowledge of its characteristics is therefore required.
