Kawasaki disease--atypical presentation.

Kawasaki disease, an acute systemic vasculitis of unknown etiology, is the leading cause of acquired heart disease in children in many parts of the world. It predominantly affects children under 5 years of age and is diagnosed clinically by the presence of characteristic clinical signs. Atypical patients, often younger than 1 year of age, manifest few early signs, usually have an incorrect admitting diagnosis and suffer from high morbidity and mortality. We report the presentation, clinical course and follow-up of a 3-month-old infant with atypical Kawasaki disease.
