Two cases of Kawasaki disease following pneumonia

Kawasaki disease (KD) causes multisystemic vasculitis but rarely manifests with pulmonary symptoms. As its etiology is still unknown, there are no specific diagnostic tools available, and KD can be diagnosed only by the symptom pattern. The presence of unusual clinical manifestations often leads to delayed diagnosis. Here, we report two cases of KD with an initial presentation of pneumonia. KD should be consideration when there is a prolonged inflammatory reaction and progressive pneumonia unresponsive to antibiotics. (Korean J Pediatr 2009;52:615-618)
