BACKGROUND: During the outbreak of COVID‐19 many pernio‐like lesions have been increasingly reported. The aim of the study is to describe our management of these skin manifestations and to evaluate a possible correlation to SARS‐CoV‐2 infection. METHODS: All patients underwent clinical and laboratory tests to detect a possible underlying connective disease and also to specific SARS‐CoV‐2 investigations such as oropharyngeal swab and IgG‐IgM serology. RESULTS: Nine patients aged between five and fifteen years old were evaluated. Skin lesions observed were purplish, erythematous and oedematous, in some cases painful and itchy. Six out of nine had respiratory and systemic symptoms (cough, nasal congestion, chills, fever, asthenia) that preceded cutaneous findings of approximately two weeks. Concerning blood exams, three out of nine had D‐dimer weakly increased, four had ANA positivity: two with a title 1:160, one with 1:320 and one with 1:5120 and a speckled pattern. The latter patient had also ENA SS‐A positive and RF positivity, confirmed at a second check, so as to allow us to make a diagnosis of connective tissue disease. Four out of nine had aPL positivity (IgM). Reactants acute phase were all negative. Oropharyngeal swabs and serology tests for SARS‐CoV‐2 was negative (borderline in one patient for IgM). No treatment was needed. CONCLUSIONS: Even if we do not have enough data to prove it, we hypothesize a correlation between pernio‐like lesions and SARS‐CoV‐2 infection for an increased number of these lesions described during the pandemic and also because such manifestations appeared when temperatures were mild and patients were at home in isolation for the lockdown.
