6 skin alarm bells linked to covid: the Italian study


Not just cough, fever, bronchitis or pneumonia. The Covid 19 it also has other ways to manifest itself: for example the skin, with apparent “banal” skin alterations. An all-Italian study, conducted with the support of the Italian Society of Medical, Surgical, Aesthetic Dermatology and Sexually Transmitted Diseases (SIDeMaST) and published in the Journal of the American Academy of Dermatology, has identified 6 that can be an associated manifestation of the Coronavirus at different stages of the disease.

“The study – says Ketty Peris, president SIDeMaST – confirms that the skin may indicate a Sars-CoV-2 infection. This is why it is essential to check our skin even more ”. Research coordinator is Angelo Valerio Marzano, director of the School of Specialization in Dermatology and Venereology at the University of Milan.

The 6 skin phenotypes identified and which may be related to COVID-19 are: a clinical picture similar to urticaria, a morbilliform rash in both limbs and trunk, a chicken pox-like skin reaction, presence of chilblains-like lesions, vasculitis, with a vinous red color and possible ulcer formation on the lower limbs. The study was conducted on 200 patients throughout Italy.

“The average duration of the skin manifestations observed – says Marzano – was 12 days; that of the chilblains was 22 days. Furthermore, we found that chilblains were the prevalent symptom among young people and were associated with an almost always asymptomatic manifestation of the virus, while all the other phenotypes were linked to a more or less severe form “.

“In this regard – continues Marzano -, two important international works had assumed the fact that the most serious skin lesions were related to a more severe form of Coronavirus. A correspondence that, on the other hand, according to our studies, does not exist: there is no direct correlation between the severity of the skin manifestation and that of Sars-CoV-2 disease. Rather, a correlation exists between increasing age and increasing disease severity ”. For the expert it is therefore necessary to pay particular attention to precise signals that appear on the skin: they are all spies that must lead us to take a swab.
