Update on pediatric psoriasis, Part 2: Therapeutic management.

Pediatric psoriasis is an autoimmune diathesis with a complex immunologic basis. It is associated with extensive psychological morbidity and should be treated rapidly and effectively to limit psychologic effects on children. The most common trigger in childhood is upper respiratory tract infection. Once disease has occurred, treatment is based on severity and presence of joint involvement. Topical therapies include corticosteroids and calcipotriene. UV light, systemic retinoids, and cyclosporine remit cutaneous psoriatic lesions. Methotrexate sodium and etanercept benefit both skin and joint manifestations of psoriasis. Concern for psychological symptoms and psychological growth is needed in treating pediatric patients with psoriasis vulgaris.
