Multisystem inflammatory syndrome in neonate with skin lesions—A rare case report

Abstract

Multisystem inflammatory syndrome in children is a serious condition that occurs due to postinfectious immune-mediated hyperinflammatory reaction seen in children, which develops after 4–6 weeks of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection; it is rare in neonates. We present here a case of a term newborn with fever, respiratory distress, and necrotic skin lesion that gradually progressed to multisystem dysfunction. Reverse transcription polymerase chain reaction for SARS-CoV-2 was negative for both mother and the baby. SARS-CoV-2 IgG titer was negative in the mother but was found to be positive in the newborn. The diagnosis of multisystem inflammatory syndrome in neonate was made and was successfully treated with intravenous immunoglobulin and corticosteroids.
