Abstract
Recently published data on the pathogenesis and cutaneous manifestations of a new coronavirus infection (COVID-19) are presented. The most described lesions are urticarial, papulo-vesicular, erythematous rash, purpura, livedo-angiitis, as well as chilblains. Eruptions mainly appear together with main COVID-19 symptoms or a few days later. The treatment of new coronavirus infection may lead to a quick regression of skin lesions along with improvement of the general state of the patient. The review also provides data on the fact that COVID-19 patients with severe psoriasis and atopic dermatitis receiving biologic therapy (guselkumab, ustekinumab, adalimumab, secukinumab, ixekizumab, etanercept, dupilumab) and phosphodiesterase-4 inhibitors experience mild or asymptomatic COVID-19. Moreover, such patients do not develop cutaneous manifestations of COVID-19. The specific COVID-19 treatment has not been developed yet. We think that these findings might provide better understanding of mechanisms of action of biologic drugs in COVID-19.Keywords
