Skin lesions in coronavirus infection caused by the SARS-CoV-2 virus are divided into seven categories. The first category includes skin angiitis caused directly by COVID-19 infection, against which the walls of small vessels of the dermis are damaged by immune complexes circulating in the blood. Angiitis is localized on the skin of the upper and lower extremities. They look like frostbite, painful, itchy. Such manifestations usually occur in young patients with a mild course of the disease, appear in the late stages and last about 12 days. The second category includes papular-vesicular rashes, which are characterized by acute clinical manifestations in the form of chickenpox, more similar to prickly heat, occurring against a background of high fever and increased sweating.

The current COVID-19 pandemic caused by SARS-CoV-2 has become a global health emergency. Treatment of chronic inflammatory bowel disease (CIBD) according to the standards includes the use of 5-aminosalicylic acid (5-ASA), corticosteroids, cytostatics, and biological therapy. However, these treatments can weaken the immune system, which potentially puts COPD patients at increased risk of infections and infectious diseases, including COVID-19. Therefore, patients with CVD have a greater risk of developing COVID-19 and more severe clinical course, or even death, compared to the general population.

Experts refer to the third category of skin manifestations as pink lichen and papulosquamous rashes, which are infectious-allergic skin lesions associated with COVID-19 infection. The clinical feature of pink lichen in this case is the absence of maternal plaque. The fourth category includes a measles rash. To the fifth - toxicodermia. This rash is associated with individual intolerance of patients of certain groups of drugs. The sixth category of skin manifestations of coronavirus infection, scientists include urticaria, which in some cases may be a harbinger of the onset of COVID-19.

The last (seventh) category includes artificial (trophic) changes in facial tissues that occurred in patients with artificial lung ventilation and due to prolonged lying on the stomach. The classifications given were the first descriptions of skin lesions in COVID-19 and therefore different signs were given: those that were caused specifically by COVID-19, and those that arose due to various causes, in particular those associated with the treatment of the disease. Due to the fact that these lesions required different approaches in both treatment and anti-epidemic or precautionary measures, we, based on the experience of all these months of observation of patients, propose a classification of skin lesions associated with COVID-19. lay out like this
