Coronavirus: Five COVID-19 Skin Conditions Identified, Study Finds | News from the world


Five dermatoses associated with the coronavirus have been identified by dermatologists, according to a new study.

Research has been carried out on 375 patients in Spain, with the aim of drawing a picture of how the disease could manifest itself through skin symptoms.

Through the Spanish Academy of Dermatology, all dermatologists in the country have been asked to help identify patients who have had an unexplained “rash” in the past 15 days and who have suspected or confirmed COVID-19[female[feminine.

They were given a questionnaire and photos of the skin conditions were taken to detect patterns of the potential effect of the virus on the skin.

But the study authors, published in the British Journal of Dermatology, warned that in some cases it was difficult to say whether the skin conditions were directly caused by coronavirus or if they have indicated complications.

They also urged the public not to try to self-diagnose COVID-19 based on skin symptoms, since rashes and lesions are common and difficult to differentiate without medical expertise.

Frostbite-like symptoms

According to the study, 19% of the cases involved symptoms resembling frostbite, described as “acral areas of erythema-edema with a few vesicles or pustules”.

He stated that these lesions affect the hands and feet and may resemble small itchy swellings from frostbite.

They have been described as small red or purple spots caused by bleeding under the skin and generally asymmetrical in appearance.

The study indicated that they were associated with younger patients, lasted an average of 12.7 days, appeared later in COVID-19 and were associated with milder cases of the disease.

Vesicular rashes

Described as outbreaks of small blisters, often itching, that appeared on the trunk of the body, dermatologists identified “vesicular rashes” in 9% of cases.

He said they could be filled with blood, could get bigger or larger and could potentially affect people’s limbs.

Associated with middle-aged patients, they lasted an average of 10.4 days, appeared more frequently before the other symptoms and were linked to an intermediate severity of the disease.


Identified in 19% of cases, “urticarial lesions” consist of raised areas of pink or white skin and resemble a nettle rash.

Commonly called papules, these are usually itchy and can spread throughout the body, including in a few cases on the palms of the hands.

They were found to last an average of 6.8 days,

Other maculopapules

“Other maculopapules” were identified in 47% of cases and described as small, flat, raised red bumps.

They were distributed from round hair follicles in some cases and had different degrees of scaling.

The study found that the appearance was similar to that of pityriasis rosea, a common skin condition.

He said blood spots under the skin could also be present, in the form of spots or dots or on larger areas.

These conditions lasted 8.6 days on average.

They usually appeared at the same time as other symptoms of coronavirus, were associated with more severe cases, and itching was very common.

The researchers pointed out that maculopapules and urticarial lesions are common and may have many causes, which means they may not be useful in diagnosing COVID-19.

Livedo or necrosis

Identified by dermatologists in 6% of cases, life or necrosis occurs when the circulation in the blood vessels of the skin is impaired, which gives it a speckled appearance of red or blue with a mesh-like pattern.

Necrosis describes the premature death of skin tissue.

Patients have shown different degrees of lesions indicating “occlusive vascular disease”, where a narrowing or blockage of the arteries occurs, limiting blood flow to certain areas of the body.

The study added that these conditions were associated with older patients with severe COVID-19 cases, although the manifestations of the disease in this group vary.

Vivoid and necrotic lesions are relatively rare, but the authors said it was unclear whether they were directly caused by a coronavirus, or simply indicated complications.
