Skin manifestations of a new coronovirus infection COVID-19 caused by SARS-CoV-2

Abstract

The review is devoted to the skin manifestations of new coronovirus infection (SARS-CoV-2), information about which is constantly updated. However, this information has not been systematized yet. The purpose of this review is to analyze the dermatological manifestations of a new coronavirus infection. On average, 12.5—20.4% of patients with confirmed COVID-19 have developed skin manifestations. The question of whether the skin symptoms are a secondary consequence of a respiratory infection or a primary infection of the skin itself remains open at the moment. The possible mechanisms of development of skin lesions and the role of diseases of complement system and blood hypercoagulation in the pathogenesis of the disease are discussed in the article. The review also provides descriptive and clinical examples of skin manifestations in COVID-19. Since COVID-19 tends to be asymptomatic within 14 days, skin manifestations can be an indicator of infection, which leads to the timely diagnosis. In addition, doctors' awareness about skin symptoms associated with COVID-19 infection plays a big role in preventing misdiagnosis of the disease. The authors cite their own clinical сase of a patient with COVID-19 and associated skin angiitis.
