Excellent response to ustekinumab in a 9-year-old girl with severe psoriasis

Abstract

We report the case of a 9-year-old girl with severe plaque psoriasis refractory to multiple topical and systemic therapies. Physical examination revealed extensive, erythematous plaques with overlying thick scales that covered more than 80% of her body surface area, which included the face, scalp, trunk, and limbs. Because of the severity of the disease and lack of treatment response to other systemic therapies, she was treated with ustekinumab. Three weeks after ustekinumab was initiated, her psoriatic lesions fully cleared.
