Childhood psoriasis: often favorable outcome.

(1) Plaque psoriasis is the most common form of psoriasis in children. Topical agents should be tried first, especially well-tolerated products such as emollients. Topical corticosteroids are sometimes useful during exacerbations but, given adverse effects, they should only be used for short periods; (2) UVB phototherapy is an option for extensive psoriasis refractory to local treatments, but it carries a long-term risk of skin cancer. Immunosuppressants have not been well assessed in this setting, but methotrexate has been better evaluated than the others.
