Unilateral cervical mass as a main clue raising the diagnostic suspicion of Kawasaki syndrome.

Unilateral cervical mass and fever were firstly misdiagnosed as bacterial lymphadenitis in a 6-year-old child and empirically treated with antibiotics. Later the child developed the additional features of Kawasaki syndrome and received intravenous immunoglobulins at the eighth day since fever onset with progressive disappearance of the cervical mass and no cardiac sequel. Kawasaki syndrome should be considered in childhood as a relevant cause of cervical lymphadenopathy unresponding to antibiotics: its recognition at an early stage might contribute to anticipate a proper treatment and abate heart complication rate.
