Abstract:
To date，the etiology of Kawasaki disease(KD)remains unclear and no definite diagnostic test exists.The diagnosis is mainly based on its clinical features.However，pediatricians always encounter febrile children who do not fulfill the diagnostic criteria but have several findings similar to those of Kawasaki disease，and these children are said to have incomplete KD.The two diseases have similar epidemiological features，clinical presentations，laboratory profiles and treatment methods.Owing to the absence of some major criteria，incomplete KD can easily be misdiagnosed,resulting in a delayed treatment，which in turn can lead to the development of coronary artery lesions(CALs).More timely diagnosis and treatment of incomplete KD patients can improve the prognosis.

Key words: Incomplete Kawasaki disease, Kawasaki disease, Coronary artery lesions, Children
