Eczema, or atopic dermatitis, is the most common form of dermatitis. Many factors, including genetic and environmental factors, are thought to play a part in the pathogenesis of eczema. It is most commonly seen in children but can be seen in adults as well. People with eczema tend to have dry, itchy skin prone to infection. The condition is commonly known as the "itch that rashes" because dry, itchy skin leads to a rash due to scratching or rubbing the skin.
