Atopic Dermatitis (AD) or eczema refers to a chronic inflammatory skin condition, characterized by dry skin, with patches that are red and intensely itchy. These patches of eczema may ooze, become scaly, crusted or hardened.
 
In some instances eczema can be compounded by asthma, food allergies and allergic rhinitis, which is called ‘Atopic March’, which could develop over a period of years. Recognizing that a person with AD is at a higher risk of developing one of these diseases is important for parents, patients and health care providers. Knowing that a child with a slight wheeze has had a history of eczema, for example, makes it easier to diagnose the subtle onset of asthma.
