Chilblain-like lesions (CLL) coinciding with SARS-CoV-2 infection have been described. Previous systematic reviews suggest CLL are associated with younger age, an equal sex ratio, negative testing for SARS-CoV-2, and mild to no extracutaneous symptoms. A systematic review was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines on CLL coinciding with SARS-CoV-2 to clarify the demographic characteristics, clinical features, and resolution outcomes of these skin findings. One hundred twenty-eight studies, published between March 2020 and January 2022, met inclusion criteria and were summarized in this review, representing 4,982 cases of CLL. Available data showed a slight female predominance (55%, n = 2,471 of 4,472). The mean age was 25 years, ranging from 0 to 95 years. Most cases were not associated with extracutaneous signs and symptoms (63%, n = 1,649 of 2,636). Overall, 19% (n = 347 of 1,838) of patients tested positive for SARS-CoV-2 using polymerase chain reaction, serology, or tissue biopsy. Clinical course was generally benign with 80% (n = 979 of 1,224) of cases resolving and 47% (n = 204 of 432) resolving without receiving treatment. This review provides a comprehensive summary of CLL associated with SARS-CoV-2. CLL occurred at a mean age of 25 years with a slight female predominance. The majority had negative COVID-19 testing, no extracutaneous signs and symptoms, and resolution without recurrence. |
