Atopic dermatitis is an inflammatory, chronically relapsing, non-contagious and pruritic skin disorder that is very common in children but may occur at any age; it may start as early as age 2-6 months and may persist into adulthood. It is the most common form of dermatitis. Atopic dermatitis usually occurs in people whose 'atopic tendency'. This means they may develop any or all of three closely linked conditions; atopic dermatitis, asthma and allergic rhinitis. Often these conditions run within families so, the family history is useful in diagnosing atopic dermatitis in infants
