Eczema
Allergies happen when your body overreacts to something external. It could be a medication, a food, or something that you wear, but whatever causes an allergy, it sets off a reaction inside your body. That reaction puts your body on high alert, causing it to reject the allergy-causing item (known as an "allergen"). When your skin is doing the reacting, it can become red, itchy, or painful. Sometimes blisters bubble up. At other times your skin can become scaly. Some of these reactions follow common patterns, while others are more sporadic.
Skin allergies can take many forms, and can be caused by many allergens. Some people react to sunlight only after their skin has touched citrus fruit. Others will react after their skin touches a certain perfume, or a certain metal. For some allergic skin conditions, children are more likely to react. For other conditions, women are more likely to experience skin reactions. As you go through these images, you will gain insight into many of the ways allergies can cause problems with your skin. Learn about phototoxic dermatitis, lichen striatus, eczema, swimmer's itch, and many, many more allergic skin conditions. Discover what steps you can take to protect your health when your skin reacts to allergens.
Eczema is a group of itchy, inflammatory skin conditions. Another name for eczema is atopic dermatitis. Eczema may start in infancy or childhood and persist into adulthood. For others, eczema lessens with age. Eczema starts as a cluster of blisters that progresses into a thick, scaly, intensely itchy rash. There are many different types of eczema.
Atopic dermatitis is a form of eczema related to the same immune reaction that underlies allergy and asthma (atopic disease). The condition tends to be chronic.
Contact dermatitis results when allergens or irritants provoke skin inflammation. Allergens may include plants, pets, and certain foods. Irritants may include chemicals in cleaning products, beauty products, paints, and solvents. Contact with fragrances or certain fabrics may provoke dermatitis.
Dyshidrotic dermatitis results in small, fluid-filled blisters that form on the hands and feet. The blisters are intensely itchy.
Neurodermatitis (lichen simplex chronicus) is an intensely itchy rash that often occurs on the forearms, thighs, or ankles. The intense discomfort of the rash provokes scratching -- which increases itching -- prompting more scratching.
Nummular dermatitis is a coin-shaped scaly patch or sore that may occur after an injury such an insect bite, abrasion, or burn.
Seborrheic dermatitis (seborrheic eczema) causes yellow, flaky patches, usually on the scalp.
Stasis dermatitis is a rash that occurs on the lower legs when there is a problem circulation of blood and return of blood to the heart.
Eczema Herpeticum
Eczema herpeticum is a herpes skin infection that can develop on areas affected by another skin disease, usually atopic dermatitis. The picture shows a child affected by eczema herpeticum lesions superimposed on a background of atopic dermatitis.
Nummular Eczema
Nummular eczema is a type of skin condition that causes itchy, scaly, coin-shaped areas of irritation on the skin. The lesions occur due to a triggering event like an insect bite or the occurrence of dry skin in the winter. “Nummular” is derived from the Latin word “nummus,” that means small coin.
Xerosis
Xerosis is the official medical term for dryness of the skin, eyes, and mucous membranes. Mild cases of dry skin may be alleviated with moisturizers and emollient lotions and creams. More severe cases of dry skin may be an indication of a more serious condition such as dermatitis, or inflammation of the skin.
Atopic Dermatitis, a Type of Eczema
Eczema is an inflammatory skin condition. There are many different kinds of eczema, but the most common type is atopic dermatitis. Heredity plays a very big role in determining who is affected by atopic
