Covid-19 can also harm the skin. A new study recently published in the British Journal of Medicine has highlighted how the new coronavirus can also have consequences on the skin, in some cases even without other concomitant symptoms. The research was carried out in Spain in 375 patients. The Spanish Academy of Dermatology has commissioned all Spanish dermatologists to examine patients who in the last two weeks have experienced unexplained rashes among those who were positive or suspected of having contracted the virus. Dermatologists viewed the images of several patients, identifying five different skin manifestations.
The five dermatological pathologies.
Red-violet lesions similar to those described in 19% of cases.chilblains, which generally occur in winter. The study shows that this problem lasts on average 12.7 days, related to milder forms of the virus and more common among younger patients. In 9% of cases they were detected vesicular rashes , (which are slightly more specific than Covi) often itch, mainly on the trunk (but can also spread to the rest of the body). This type of rash has been observed mainly in middle-aged patients with the virus with an average severity and duration of 10.4 days on average. In 19% of cases they occurred urticaria lesions, with pinkish-white areas of skin and a duration of symptoms of 6.8 days. In 47% of the most severe patients, emaculopapular ruptures around the hair follicles. In 6% of cases they occurred vasculitic lesions caused by impaired circulation of blood vessels (more common in elderly patients). The Spanish study is very comprehensive because it describes Covid’s skin manifestations in detail – he comments Sebastiano Recalcati, a dermatologist at the Alessandro Manzoni hospital in Lecco, although it has an important limit: only 50-60% of the patients studied had tested positive for hyssop, the rest had a clinical diagnosis of suspected Covid-19. After all, in Spain, as happened in Italy, the swabs were made only to those who showed significant symptoms. Just Recalcati, involved in the first line of this emergency, had published the first scientific article related to COCID-19-related skin manifestations in the prestigious Journal of the European Academy of Dermatology and Venereology, already describing in March the skin manifestations of patients with Covid positives present in 20% of patients: erythematous rash, urticaria, gallbladder lesions.
Chilblains: increasingly reported worldwide
Among the skin manifestations, chilblains deserve special attention because reports from around the world show that they are typical of children and adolescents who do not actually show symptoms. A recently published study tells the story of 14 children and young adults who visited the Alessandro Manzoni hospital in Lecco who experienced chilblain-like skin symptoms. The authors suspect that there is a link to COVID-19. The buffer was performed in some patients, but negative. We believe chilblains may be a late manifestation of the virus, Sebastiano Recalcati adds, even a month after infection, making swabs negative. We suspect that children’s more active immune systems would favor this immune-mediated manifestation. The key will be the serological test: if there is immunological memory, it will be known. Certainly, for the moment we cannot rule out anything, not even that it is a new virus. The data is preliminary. In the New York Times, San Francisco dermatologist Lindy Fox says she visited dozens of chilblain patients out of season when she saw 4-5 in a year at most. All the patients who have never suffered something like this, he says. The same is true at Massachusetts General Hospital in Boston, and doctors insist on protecting those who experience this problem even in the absence of other symptoms. Also across the ocean, children and young adults suffer from chilblains. Here too, the swabs were almost always negative. The lesions can be itchy, rarely painful, and usually go away on their own within a few weeks.
