Adult recurrence of kawasaki disease mimicking retropharyngeal abscess

Abstract

Kawasaki disease (KD) is an acute, self-limited vasculitis of unknown etiology that occurs predominantly in young children (≤5 years of age). We herein report the case of an 18-year-old Japanese man with a history of incomplete KD during infancy; later, despite an initial diagnosis of retropharyngeal abscess, he was ultimately diagnosed with retropharyngeal edema associated with recurrent KD. Adult-onset or recurrent KD is an uncommon event, and retropharyngeal edema is a rare manifestation of this disease. Internists should be aware of the possibility of KD that mimics a retropharyngeal abscess, even in adult patients.
