Our objective was to determine the association between skin lesions in children and SARS-CoV-2 infection, analyzing others possible infectious/autoimmune etiologies. Observational, multicenter, cross-sectional study, about children with skin manifestations from April to May 2020. The diagnosis of SARS-CoV-2 was performed by PCR in nasopharyngeal exudate and/or presence of antibodies by serology. Sixty-two children were included, 9 (14.5%) presented positive antibodies to SARS-CoV-2, with no positive PCR to SARS-Cov-2 in those patients in whom it was made. Patients with positive serology to SARS-CoV-2 presented chilblains and/or vesicular-bullous skin lesions more frequently (66.7% vs. 24.5%, p=0.019). Generalized, urticarial and maculopapular rash was more common in patients with negative antibodies (37.7 vs. 0%, p=0.047), others pathogens were isolated in 41.5% of these patients. There were no significant differences in the positivity for autoantibodies between both groups. In our study, the presence of chilblains-like and/or vesicular lesions were significantly related to SARS-CoV-2 previous contact.
