The aim of this paper is to summarize reports of CLL coinciding with SARS-CoV-2 infection to clarify the prevalence, clinical relevance, and prognostic value of these lesions. A literature search was conducted using the Embase, Pubmed, and Scopus databases from December 2019 to June 16, 2020 using the search terms (\u201cCOVID-19\u201d OR \u201ccoronavirus\u201d OR \u201c2019-nCoV\u201d OR \u201cSARS-CoV-2\u201d) AND (\u201cchilblain-like\u201d OR \u201cCOVID toes\u201d OR \u201cacral\u201d). Papers that described skin changes in patients with suspected or confirmed COVID-19 were included. A total of 31 papers were summarized, representing 813 cases of CLL. Available data suggests an equal gender distribution, mean age of 21 years, and median age of 14 years. Mild extracutaneous symptoms were reported in 53% of cases and 47% were asymptomatic. CLL occurred an average of 16 days after extracutaneous symptoms. Patients with CLL were positive for SARS-CoV-2 in 15% of cases. Lesions were mainly described as asymptomatic and\/or pruritic erythematous to violaceous acral macules and plaques. Partial or complete resolution occurred in 85% of cases in a mean of 13 days. The most common histologic findings were perivascular and perieccrine superficial and deep lymphocytic infiltrates. Although a causal relationship between CLL and SARS-CoV-2 has not been confirmed, the temporal association and 15% positive SARS-CoV-2 rate in affected individuals should not be ignored.<\/jats:p>","DOI":"10.1177\/12034754211004575","type":"journal-article","created":{"date-parts":[[2021,4,14]],"date-time":"2021-04-14T01:13:19Z","timestamp":1618362799000},"page":"627-633","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":14,"title":["Chilblain-Like Lesions (CLL) Associated With COVID-19 (\u201cCOVID Toes\u201d): A Systematic Review"],"prefix":"10.1177","volume":"25","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0834-3783","authenticated-orcid":false,"given":"Nadia","family":"Kashetsky","sequence":"first","affiliation":[{"name":"Faculty of Medicine, Memorial University of Newfoundland, St. John\u2019s, NL, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1058-9413","authenticated-orcid":false,"given":"Ilya M.","family":"Mukovozov","sequence":"additional","affiliation":[{"name":"Department of Dermatology and Skin Science, University of British Columbia, Vancouver, BC, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"James","family":"Bergman","sequence":"additional","affiliation":[{"name":"Department of Dermatology and Skin Science, University of British Columbia, Vancouver, BC, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2021,4,13]]},"reference":[{"key":"bibr1-12034754211004575","unstructured":"World Health Organization2020.
