[Unusually early onset of Kawasaki syndrome with coronary artery aneurysms].

Kawasaki disease is a multisystem illness that has been described throughout the world. It affects children with a peak frequency in the 6-month to 5-year group. Besides the typical clinical findings and specific laboratory changes during the initial phase of acute illness there are obligatory cardiovascular manifestations due to a generalized microvasculitis. Above all the coronary arteritis resulting in the formation of aneurysm may complicate a primarily good prognosis (causing death in 1-2% of the cases). The present case report describes a coronary artery involvement in a young 1 1/2-month-old infant with Kawasaki disease.
