The term "Covid toes" refers to a specific type of skin lesion known as pernio-like acral lesions. These lesions are characterized by painful, swollen, and possibly discolored skin, typically occurring on the toes and fingers. They resemble chilblains, which are inflammatory reactions to cold or damp conditions.

In the context of COVID-19, these lesions have been observed as one of the dermatological manifestations of the virus, particularly among individuals who may not display other prominent symptoms of the disease. The underlying mechanism is thought to be related to the body’s immune response to the virus, leading to localized inflammation in the digits.

Other skin lesions, such as macropapular rashes, skin nodules, and scaly plaques, are not typically associated with COVID-19 in the same way as pernio-like lesions. While they may be seen in various dermatological conditions, they do not share the specific characteristics or the association with COVID-19 that "Covid toes" do.
