Atopic eczema (eczema, atopic dermatitis, diffuse neurodermatitis, endogenous eczema) is one of the most common skin diseases of our time—not only in childhood. The prevalence of this disease has increased dramatically over the past decades, although the reasons for this increase are not known. Eczema occurs anywhere in the world, not only in industrialized countries. It occurs at any age, not only in childhood, and approximately two-thirds of children affected will suffer from this disease when they are grown up.
