Kawasaki disease is an acute febrile illness, causing mucosal inflammation, skin rash, and cervical lymphadenopathy, recognized most often in children younger than 4 yr of age. It was first described by Dr. Tomisaku Kawasaki in Japanese literature in 1967 (1), and then in English in 1974 (2). The disease is of unknown etiology that produces a systemic vasculitis, which is most severe in the medium-sized arteries, and especially prominent in the coronary arteries. This can be associated with considerable morbidity and mortality, mostly the result of myocardial involvement and coronary artery complications such as aneurysm, calcification, and stenosis. In Japan as well as in North America, Kawasaki disease is presently a leading cause of acquired heart disease in children (3).
