 Allergic Conditions: Eczema and Atopic DermatitisEczema, or atopic dermatitis, is a common allergic reaction often affecting the face, elbows and knees. This red, scaly, itchy rash is usually seen in young infants, but can occur later in life in individuals with personal or family histories of other allergic conditions - such as asthma or hay fever. In infants, eczema usually appears as tiny bumps on the cheeks. Older children and adults often experience rashes on the knees or elbows (often in the folds of the joints), on the backs of hands or on the scalp. Itching is the hallmark symptom and can sometimes be very intense. Eczema can appear very dry, with flaking skin, or can have lesions that ooze - often a sign of a bacterial infection caused by scratching. Identifying the cause of the itch is essential in relieving the dermatitis. Common triggers include allergens, overheating or sweating, emotional stress, eating certain foods and contact with irritants such as wool, pets, soaps or other agents.
An allergist/immunologist is the best-qualified medical professional to diagnose and treat allergic skin conditions. To locate an allergist in your area, visit the AAAAI's Physician Referral Directory.
