Definition: Kawasaki disease or mucocutaneous lymph node syndrome is an acute exanthematous illness of childhood of unknown etiology with a recent marked increase in incidence.
Kawasaki disease (KD) is an inflammatory condition of unknown etiology. It involves mainly the skin, mucous membranes, lymph nodes, and myocardium. Clinical and epidemiologic features of KS are consistent with an infectious cause. The essential lesion is an arteritis and periarteritis initially involving small arteries and later the medium and large vessels.
