Kawasaki disease in a 37-year-old patient: Typical features, atypical age: A case report

Background Kawasaki disease (KD) is an acute vasculitis of unknown etiology that typically affects children under five years of age. Adult presentations are exceedingly rare and often atypical, leading to diagnostic delays. Case report We report a case of a 37-year-old Vietnamese male presenting with findings fulfilling all five of the classic diagnostic criteria for KD. Prompt recognition and treatment with intravenous immune globulin (IVIG) and high dose aspirin led to rapid clinical improvement and prevention of coronary complications. Why should an emergency physician be aware of this? This case underscores the importance of maintaining a high index of suspicion for KD across all age groups and highlights the uncertainties surrounding the optimal aspirin dosing in adults.
