Kawasaki Disease Presenting as Parotitis in a 3-Month-Old Infant

A male infant aged 3 months and 1 week had persistently high fever with parotitis that was unresponsive to antibiotics. Mumps was identified by serologic study, but he was finally diagnosed by clinical features as having Kawasaki disease and echocardiographic findings on the 9th day of fever. Parotitis, which is unresponsive to antibiotics, should be considered Kawasaki disease even though typical symptoms are not present.
