Eczema is a very common skin disease and is also known as atopic dermatitis. Eczema itches, and patients scratch frequently resulting in bacterial colonization of the skin. Eczema appears as red, itchy papules (bumps) and plaques and may look different in babies, young infants and older children and adults. Babies have eczema on their cheeks, trunk and sparing of the diaper area. Young children usually have eczema on the back of the neck, flexor areas of the arms and legs, wrists, hands, ankles and feet. In older children and adults, the back of the neck, flexor extremities and hands are commonly involved. Long-standing lesions may be thick, raised and itchy.
