Objectives:

To describe the most frequent dermatological conditions observed in COVID-19 patients and to determine whether their presence could be used to establish an early diagnosis or to predict the progression of the infection.

Methods:

There was a review in PubMed/MEDLINE and EMBASE of all the articles that had been published between January 1st and November 1st, 2020, with the search terms focused on “SARS-CoV-2”, “COVID-19” and “Skin diseases”.

Results:

Eighty three studies met the inclusion criteria. Skin lesions have been reported in 0.2 % of the patients. The most frequently reported dermatoses were: maculopapular/ morbilliform rashes, urticaria and angioedema, chilblain-like acral pattern, and vesicular lesions. Among researchers, there are differences of opinion about a possible diagnostic or prognostic value of the skin diseases that are associated to the infection.

Conclusions:

It is advisable to consider the diagnosis of SARS-CoV-2 infection in patients who call the doctor for skin lesions, urticaria, or angioedema, with or without other symptoms of the infection, especially if there is a previous history of recent exposure to other infected subjects.
