Kawasaki disease (KD) is an acute illness of unknown cause that affects infants and children. The diagnosis is confirmed in patients with prolonged fever and four of the following clinical features: (1) nonexudative conjunctivitis; (2) oral cavity changes; (3) rash; (4) extremity changes; and (5) cervical adenopathy. Complications of KD include coronary artery aneurysms, which may lead to myocardial infarction, chronic coronary insufficiency, or death. We describe a series of 83 patients with KD in whom 43 (52%) of 83 developed cervical adenopathy during their acute illness. Eighteen (42%) of these 43 patients were initially misdiagnosed as having cervical adenitis and were treated with antibiotics. The otolaryngologist may see these patients in referral and should consider the diagnosis of KD in patients with cervical adenopathy, prolonged fever, signs of mucosal inflammation, or rash. Early diagnosis and intravenous treatment with high-dose gamma-globulin is effective in reducing the prevalence of coronary artery abnormalities.
