A literature search in the electronic databases PubMed, Scopus and Web of Science was conducted up to 30 April 2020, using the term 'COVID-19' in combination with 'skin', 'cutaneous manifestations', 'eruption', 'rash', 'exanthem', 'urticarial', 'chilblain', 'livedo' and 'purpura' in order to collect reports of skin manifestations described in patients with COVID-19. Given the limited number of papers, we included all of the available clinical reports dealing with this very recent topic, most of which concerned individual cases or small case series. Articles were selected based on title and abstract. Full texts were then carefully read to evaluate the article content. Articles from the references cited in the retrieved papers were also manually searched as appropriate.
