- Eczema is a term for a group of medical conditions that cause the skin to become inflamed or irritated. The most common type of eczema is known as atopic dermatitis, or atopic eczema.
- Atopic refers to a group of diseases with an often inherited tendency to develop other allergic conditions, such as asthma and hay fever.
- Eczema affects about 10% to 20% of infants and about 3% of adults and children in the U.S. Most infants who develop the condition outgrow it by their tenth birthday, while some people continue to have symptoms on and off throughout life. With proper treatment, the disease often can be controlled.
What Are the Symptoms of Eczema?
- No matter which part of the skin is affected, eczema is almost always itchy. Sometimes the itching will start before the rash appears, but when it does, the rash most commonly appears on the face, back of the knees, wrists, hands, or feet. It may also affect other areas as well.
- Affected areas usually appear very dry, thickened, or scaly. In fair-skinned people, these areas may initially appear reddish and then turn brown. Among darker-skinned people, eczema can affect pigmentation, making the affected area lighter or darker.
- In infants, the itchy rash can produce an oozing, crusting condition that happens mainly on the face and scalp, but patches may appear anywhere.
