A case of multisystem inflammatory syndrome in children (MIS-C) mimicking Kawasaki disease

Introduction: Severe acute respiratory syndrome coronavirus-2 infection has emerged as a multisystem disorder during the pandemic of Coronavirus disease of 2019 (Covid-19). Multisystem inflammatory syndrome of children (MIS-C) is a rare grave complication of Covid-19 due to immunodysregulation.

 

Case Presentation: We present a 14-year-old boy who had fever, cardiac and gastrointestinal symptoms, mucocutaneous manifestations and cervical adenopathy with a background of recent asymptomatic Covid-19 infection. Inflammatory and cardiac biomarker panels were raised in the absence of other microbial causes of inflammation.

 

Discussion: Although there were overlapping features of Kawasaki disease, the ultimate diagnosis was MIS-C. He was successfully managed with immunomodulatory therapy.
