Atopic Dermatitis - Symptom, Causes & Treatment
Atopic dermatitis is a common, potentially debilitating condition that usually starts in early infancy and is typified by pruritus, eczematous lesions, xerosis (dry skin), and lichenification on the skin. The condition is characterized by a chronic skin disease characterized by itchy, inflamed skin.
Atopic dermatitis is often referred to as "eczema," which is a general term for the many types of dermatitis.
Atopic dermatitis is very common in all parts of the world. It affects about 10% of infants and 3% of the total population in the United States. Atopic dermatitis most often affects infants and young children, but it can continue into adulthood or first show up later in life.
The skin lesions observed in atopic dermatitis vary greatly, depending on the severity of inflammation, different stages of healing, chronic scratching and frequent secondary infections. Acute lesions are papules and vesicles on a background of erythema.
