Recalcitrant palmoplantar pustular psoriasis treated with etanercept.

We report a 10-year-old boy presenting with palmoplantar pustular psoriasis, resistant to topical and systemic treatments, who was successfully treated with subcutaneous etanercept (0.4 mg/kg) twice a week for 1 month. Maintenance therapy was extended for 18 months in combination with near ultraviolet light therapy without any adverse effect. Etanercept may be a safe and effective alternative for severe palmoplantar pustular psoriasis in children.
