Hair loss as a sign of Kawasaki disease

Kawasaki disease is a multi system disorder with varying clinical expressions. This disease is an acute systemic vasculitis of unknown etiology that has recently recognized as a leading cause of acquired heart disease in children of many developed countries. We describe an unusual instance of hair loss in a patient with Kawasaki disease. A 26 months old boy developed prolonged high fever, bilateral conjunctival infection, arthralgia and erythromatosis skin rash. He was admitted to the hospital with the diagnosis of Kawasaki disease. Laboratory results included an erythrocyte sedimentation rate [ESR] above 100 and platelet count > 1000,000. The patient developed acute and unprovoked scalp hair loss. He was treated with intravenous immunoglobulin [IVIG] 2 g/kg and aspirin 100 mg/kg/day with complete improvement of signs and symptoms.
