Cutaneous manifestations of COVID-19 in infected patients are poorly characterized.Objective: To summarize retrospectively the skin features of COVID-19 infection and to analyze the skin rash incidence rate, clinical onset time, cutaneous manifestations, pathological characteristics and relationship with the novel coronavirus pneumonia severity.Methods: The literature up to Sep 20, 2020, were searched and analyzed. Information on clinical features including skin manifestations, disease severity, stage and onset day, and cutaneous pathological characteristics was extracted. Data were analyzed using descriptive non-parametric statistics. For categorical data, the number and percentage of patients are presented. A Spearman correlation test was used to analyze the associations between rash type, rash onset and severity of COVID-19. All statistical analysis was performed with IBM SPSS software (version 20) using two-tailed tests. P values < 0.05 were considered statistically significant.Results: Twenty-three cases of COVID-19 patients with cutaneous manifestations from seven reports were collected. Inflammatory dermatosis, skin vasculitis and vascular dermatosis were the main lesion types of COVID-19 patients. Microvascular and endothelial cell injury, perivascular lymphocytic infiltrate, thrombosis, extremely dilated vessels and prominent deposits of C5b-9 were the main dermatologic pathological changes. The onset day analysis showed that out of 19 patients, 63.2% of cutaneous manifestations were within 10 days, 21.1% in 10– 20 days and 15.8% were 20 days after the time the patient presented with COVID-19 main symptoms. Spearman rho analysis found no correlation between skin rash type, onset day and COVID-19 severity.Conclusion: COVID-19 induced skin changes are one of the manifestations of immune responses to the novel coronavirus. Clinical and pathological characteristics were identified as dermal inflammatory reactions and/or skin vascular injury. External or systematic use of anti-inflammatories, protection of blood vessels and circulation-improving medicines should be considered in the skin treatments for novel coronavirus pneumonia patients.Keywords: COVID-19, skin manifestations, diagnosis, treatment
