Kawasaki disease: a diagnostic challenge.

Kawasaki disease (KD) is an acute, self-limited, febrile, multi-system vasculitis that predominantly affects the the pediatric population, and is the leading cause of acquired heart disease in children. No etiologic agent for the disease has been identified, there are no diagnostic tests available, and the diagnosis is established by fulfilling a defined set of clinical criteria. We report on a 9-year-old boy who presented initially with symptoms felt to represent a streptococcal infection. He was subsequently shown to meet the criteria for KD, developed cardiac complications of the disease and subsequently demonstrated recovery over a year's period of time. The diagnostic criteria for KD, differential diagnosis, pitfalls in diagnosis, therapeutic recommendations and outcomes are discussed with relevance to this case.
