Polymorphism of COVID-19 dermatological manifestations: Pandemic experience

Although the incidence of COVID-19 infection is decreasing, the clinical experience gained during the pandemic remains relevant. In this article, we present clinical cases from our own practice to describe non-standard variants of the development of COVID-19-associated skin pathology in patients of different age groups and during different periods of the infectious process. The conducted analysis of the presented cases revealed the following: systemic pathological processes caused by COVID-19 lead to the development of dermatological symptoms; different strains of SARS-CoV-2 can cause different dermatological symptoms in the same patient; skin rashes appeared as a manifestation of post-Covid syndrome may recur in case of COVID-19 reinfection; immune deviations that developed after COVID-19 infection subsequently lead to clinical pathomorphism of skin diseases; vaccination against COVID-19 may trigger relapses of chronic dermatoses.
