Diagnosis and management of psoriasis in children.

Psoriasis is increasing in both children and adults. The association of comorbidities, specifically obesity and other components of the metabolic syndrome, are also increasing. The precise cause is unknown but genetic and complex immunologic factors play a role in the development of the disease and its comorbidities. There are multiple clinical variants, and the severity of the disease can range from mild localized lesions in most patients to severe generalized involvement in some. Most patients with mild to moderate disease can be controlled with topical treatments.
