As the Coronavirus pandemic grows (COVID-19), More viral infections appear, early in the epidemic, people with HIV reported COVID-19 On the symptoms of fever, cough and difficulty breathing, and at a later time, other symptoms were added, such as loss of sense of taste, loss of sense of smell, and mouth lesions in children.

A team of dermatologists in Spain and Italy say ischemic heart lesions, similar to swollen fingers, have been reported worldwide throughout the pandemic. COVID-19.

To access the results of the study, which was published in the journal ” the Journal of Clinical and Experimental Dermatology“After a comprehensive review of articles published in the literature, the team summarized the current knowledge about the skin manifestations of Corona in children, the personal experience of dermatologists in Europe.

Swollen fingers like lesions

Fingers swollen lesions are a painful and itchy lump on the skin, usually appearing on the hands and feet, and it results from poor blood circulation in the skin upon exposure to cold.

The frostbite-like lesions associated with the Coronavirus are characterized as a swollen or ulcerated skin lesion of the toes and soles of the feet, and appear less frequently on the fingers and hands.

The lesions are most common in children, teenagers, and young adults, with most patients having excellent health and mild symptoms, and the recovery period in all cases is 4 to 8 weeks.

Since (March) 2020, several scaly lesions or similar reports of swollen fingers have spread on social media and Google trends, and many people searched for keywords such as “swollen fingers,” “toes,” “fingers,” and lesions related to “Coronavirus” ” in France.

However, the first published study and a possible case of Corona disease occurred, such as frostbite-like lesions in Italy, followed by some reports of similar cases in Spain and the Middle East, and patients who reported the lesions associated with Corona, were mostly young, and restricted to Homes due to lockdown orders, and with no prior case history.

In Spain, doctors reported cases of “false finger swelling” in 19% of 375 patients with skin manifestations of COVID-19Moreover, 277 cases reported in France with frostbite-like lesions were mostly confirmed or suspected cases of COVID-19.

Common in children and teenagers

The lesions most commonly appear in children and adolescents who are otherwise healthy, however, it is rarely seen in children younger than 10 years old.

In 74 to 100% of cases, the lesions appeared on the feet. Multiple, round lesions usually affect the entire toe with a clear demarcation. In some cases, the lesions may become dark purple with black scales.

Children and adolescents who develop the lesions are usually asymptomatic, but local pain and itching may occur. Moreover, all children and adolescents had positive health outcomes and had no complications, and the reported recovery period ranged from 12 days to more than eight weeks.

Researchers have elucidated some of the pathogenic mechanisms around how finger swelling is related to COVID-19.

First, patients with severe corona have a poor interferon response (IFNType 1 and increased tumor necrosis factor and interleukin production.

The team explained that patients with swollen fingers exhibit a strong antiviral response, thus reducing virus replication, however, an early response can lead to changes in the microangiopathy, resulting in the appearance of swollen-like lesions.

Finally, the researchers note that a change in habits during the pandemic and lockdown could be related to frostbite, and this could be due to walking barefoot at home, lack of physical activity, and stress.
