Far east scarlet-like fever masquerading as adult-onset Kawasaki disease

Abstract

A previously healthy 31-year-old man was referred to us with refractory septic shock accompanied by bilateral conjunctival congestion and erythema of his right lower limb. Nine days after admission, he had bilateral desquamation of the fingertips, and his presentation satisfied the criteria for Kawasaki disease. A serological examination was positive for Yersinia pseudotuberculosis, and he was diagnosed with Far East scarlet-like fever (FESLF). Interestingly, his 11-month-old baby boy had similar symptoms around the same time, indicating the intrafamilial transmission of the pathogen. We should consider FESLF when we encounter a familial occurrence of systemic manifestations of Kawasaki disease.
