Kawasaki Syndrome, mucocutaneous lymp node syndrome
A syndrome of unknown origin, mainly affecting young children, that causes fever, reddening of the eyes (conjunctivitis), lips and mucous membranes of the mouth, ulcerative gum disease (gingivitis), swollen glands in the neck (cervical lymphadenopathy), and a rash that is raised and bright red (maculoerythematous) in a "glove-and-sock" fashion over the skin of the hands and feet which becomes hard, swollen (edematous), and it peels off.

It is also called mucocutaneous lymph node syndrome, a name that is quite descriptive because the disease is characterized by the typical changes in the mucus membranes that line the lips and mouth and by the enlarged and tender lymph glands.

Kawasaki disease affects the blood vessels and is now the main cause of acquired heart disease in children. It is most common in people of Asian descent, and it is more common with males than with females.

The syndrome was first described in the late 1960's in Japan by the pediatrician Tomisaku Kawasaki.
