In many children, the exact cause of the eczema is not clear and treatment depends on regular use of moisturizer and topical medicines to dampen down the inflammation. Patients with the faulty filaggrin gene often have hand eczema with excessive little lines on the skin of their palms. Adolescents and young adults typically have the rash in the same locations as children, as well as on the hands and feet. Children are prone to have the rash at the bends of the elbow joint, wrists, behind the knees and behind the ears. In infants, eczema often appears on the face. It may “weep” or leak fluid that crusts over when scratched, which means that it is also infected. Yet there are some differences that help in the diagnosis of specific conditions. Itching, redness and swelling are common to most skin allergies. Test your knowledge about contact dermatitis. Test your knowledge about skin allergies. Keep pace with the latest information and connect with others. Skin conditions are one of the most common forms of allergy treated and managed by an allergist / immunologist, a physician with specialized training and expertise to accurately diagnose your condition and provide relief for your symptoms. It does not respond to typical angioedema treatment with antihistamines or adrenaline so it is important to see a specialist to screen for HAE and other genetic conditions. Hereditary angiodema (HAE) is a rare, but serious genetic condition involving swelling in various body parts including the hands, feet, face, intestinal wall and airways. Most cases do not have an identifiable cause. Chronic recurrent angioedema is when the condition returns over a long period of time, with each episode lasting hours to several days. Acute angioedema is commonly caused by an allergic reaction to medications or foods. Angioedema is called "acute" if the condition lasts only a short time such as minutes to hours. Angioedema many times occurs in soft tissues such as the eyelids, mouth or genitals. It is often seen together with urticaria (hives). Although they are often uncomfortable and sometimes painful, hives are not contagious.Īngioedema is swelling without itching in the deep layers of the skin. Chronic urticaria can last for many months or years. However, in rare hereditary diseases that cause chronic urticaria, genetic tests are helpful. Chronic urticaria is rarely caused by specific triggers and so allergy tests are usually not helpful. It can also be triggered by non-allergic causes such as heat or exercise, as well as medications, foods, insect bites or infections. Acute urticaria occurs at times after eating a particular food or coming in contact with a particular trigger. There are two kinds of urticaria, acute and chronic. Swelling without itching in deep layers of the skin is called angioedema. This causes small blood vessels to leak, which leads to swelling and itching. Hives are an inflammation of the skin triggered when the immune system releases histamine. The allergic reaction can come from actually touching the plant, or by touching clothing, pets or even gardening tools that have come in contact with the oil. The red, itchy rash is caused by an oily coating covering these plants. For instance, if you have a nickel allergy and your skin comes in contact with jewelry made with even a very small amount of nickel, you may develop red, bumpy, scaly, itchy or swollen skin at the point of contact.Ĭoming in contact with poison ivy, poison oak and poison sumac can also cause allergic contact dermatitis. This order of progression is called the atopic march.Īllergic contact dermatitis occurs when your skin comes in direct contact with an allergen. Eczema is often linked with asthma, allergic rhinitis (hay fever) or food allergy. Unlike with urticaria (hives), histamine is not the only cause of the itch of eczema so anti-histamines may not control the symptoms. In about half of patients with severe atopic dermatitis, the disease is due to inheritance of a faulty gene in their skin called filaggrin, although this is affected by your race and ethnicity. Also, some young children with eczema can flare with a particular food. One explanation for eczema is thought to be due to “leakiness” of the skin barrier, which causes it to dry out and become prone to irritation and inflammation by many environmental factors. It affects one in five infants but only 10% of adults. When an allergen is responsible for triggering an immune system response in the skin, then it is an allergic skin condition.Įczema is the most common skin condition, especially in children. These include immune system disorders, medications and infections. Irritated skin can be caused by a variety of factors.
