The novel coronavirus disease 2019 (COVID-19) is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and has developed into a pandemic. A unique challenge of this pandemic has been the emergence of multisystem inflammatory syndrome in children (MIS-C), a rare post-infectious hyperinflammatory disorder associated with SARS-CoV-2. This syndrome is characterized by overwhelming systemic inflammation, fever, hypotension, and cardiac dysfunction. This disorder may also have features overlapping with Kawasaki disease (KD), macrophage activation syndrome (MAS), and toxic shock syndrome (TSS). The goal of this review is to outline the presenting features, presumed immunopathogenesis, management, and outcomes of patients with MIS-C.
