Abstract: Objective For early diagnosis of Kawasaki disease(KD) and to decrease the misdiagnosis rate，this article analyzed clinical features of Kawasaki disease in the children above 5 years. Methods The clinical data of children above 5 years suffering from Kawasaki disease, whom hospitalized in tianjin pediatrics hospital from 2006 to 2010,were retrospectively analyzed and compared with the data of children under 5 years with KD。The contrast items included sex ratio,clinical situation,laboratories and physical examination,atypia/incomplete KD ratio,IVIG resistant ratio and coronary artery lesion(CAL) incidence. Results There were no differences in sex ratio, atypia KD ratio,IVIG resistant ratio and CAL．Skin of perianal area appeared flush and succedented desquamation was benefit to diagnosis of KD aged above 5 years. BCG vaccination scar appeared flush was not recorded in the patients above 5 years. Incidence rate of lymphadenectasis was higher in the patients above 5 years(p<0.05).The incidence of CAL with atypia /incomplete KD aged above 5 years was higher(80%)。Conclusion Lymphadenectasis and flush succedented desquamation of perianal area were frequently observed in the children aged above 5years. Atypia /incomplete KD aged above 5 years presented higher incidence of CAL than typical patients.KD should be regarded with differential diagnosis in fever unknow cases whose age above 5 years.
