Besides the principal respiratory symptoms, the COVID-19 has been associated with an important array of dermatological manifestations However, it is not always easy to distinguish whether these skin manifestations are the result of a direct action of the virus on epidermal and/or dermal cell populations, represent a paraviral phenomenon or are a rather fortuitous association In this review the principal cutaneous manifestations associated with COVID-19 are described as well as their eventual value in terms of diagnostic aid or as prognostic factor The palmoplantar ischemic pseudo-chilblains lesions are the most frequently observed and are useful for epidemiological purposes The disseminated vesicular eruptions affect about 23 % of the patient and may witness an initial COVID-19 infection, whereas the vasculitic lesions are rather rare but are currently considered as a factor of bad prognosis
