[Skin manifestations of COVID-19 and after COVID-19 vaccination]

Coronavirus disease 2019 (COVID-19) is a systemic disease induced by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that frequently presents with skin manifestations. The five most common skin lesions are pseudo-chilblain and maculopapular, urticarial, vesicular, and livedo/necrotizing skin lesions. These skin lesions are of diagnostic and prognostic relevance. For example, in children, typical skin lesions may indicate a life-threatening inflammatory syndrome, which rarely occurs after corona infection. Skin lesions have also been described after COVID-19 vaccination. These usually show an uncomplicated, self-limiting course and therefore do not represent a contraindication for completing the vaccination status in the vast majority of cases.
