Data on multisystem inflammatory syndrome in children (MIS-C) related to 
coronavirus disease-19 (COVID-19) is increasing in the current COVID-19 
pandemic. We present a 16 year old male who was hospitalized in July 2020 under 
adult medical service due to Kawasaki-like disease symptoms. Diagnosis of MIS-C 
related to COVID-19 was established by clinical features, elevated inflammatory 
markers, and positive SARS-COV 2 immunoglobulin G. We encourage all clinicians 
especially who practice adult medicine to be familiar with signs and symptoms of 
MIS-C to avoid delayed diagnosis and complications.
