Eczema is a form of dermatitis , or inflammation of the upper layers of the skin. There are different types of dermatitis, and the disorder can have many causes and occur in many forms. Generally, dermatitis describes swollen, reddened and itchy skin. Approximately 10 percent to 20 percent of the world population is affected by this chronic, relapsing, and very itchy rash at some point during childhood. Fortunately, many children with eczema find that the disease clears and often disappears with age. In general, atopic dermatitis will come and go, often based on external factors. Although its cause is unknown, the condition appears to be an abnormal response of the body's immune system . People with eczema often have a family history of the condition or a family history of other allergic conditions, such as asthma or hay fever. Eczema might look different in different persons, and may occur in different parts of the body to different person. In adults, eczema most often develops on the hands and elbows, and in "bending" areas such as the inside of the elbows and back of the knees. In young children, eczema most often develops on the elbows, knees, face, neck, and scalp.
