MIS-C vs Incomplete Kawasaki's Disease in a 12-year-old Female: A Case Study.

Abstract

Multisystem inflammatory syndrome in children (MIS-C) is a rare but severe post-infectious complication of SARSCoV- 2 that seems to occur most frequently two to six weeks after infection. MIS-C can present very similarly to Kawasaki's disease (KD) with symptoms such as a skin rash in addition to a prolonged fever. Here we present a case of a 12-year-old African American/Black female with incomplete KD presenting similarly to MIS-C. The patient presented with prolonged fever, eventually worsening to shock and cardiac dysfunction. We further review the similarities and differences between incomplete KD and MIS-C. Due to their similarities, it is important to keep these diagnoses on the differential when a child presents with a prolonged fever.
