Atopic Eczema

Atopic eczema (or atopic dermatitis) is an inflammation of the outer layer of the skin accompanied by itching. It most often develops in people with a history of hay fever or asthma, as well as in those who have family members with this condition.

The main symptom is the presence of redness typically located on the arms and behind the knees, although it can appear anywhere on the body. This condition is particularly common in infants.

The diagnosis is made by the doctor through a simple examination of the skin, especially if there are already cases in the family.

The causes of atopic eczema are multiple. Firstly, there is a genetic predisposition, so some people are at higher risk of developing atopic dermatitis than others. The mechanism responsible is a change in the structure of the skin that makes it more permeable to allergens and other irritating substances. This is why climate and irritants (such as shower soap, for example) can also promote the occurrence of eczema.

The treatment involves avoiding the use of soap and products that irritate the skin. Applying an anti-inflammatory cream (corticosteroid) can treat areas affected by eczema, and in rarer cases, treatment with ultraviolet light (phototherapy) is used.
