Guidelines differ on the necessity of a history of atopy as prerequisite for a diagnosis of eczema but agree that the diagnosis is made clinically. Most cases of eczema involve childhood onset with up to 60% of cases developing within the first year of life. In Canada, approximately 10% of children develop atopic dermatitis during childhood, but higher rates have been reported elsewhere. Adult cases are less common but not rare. In the event of childhood onset, spontaneous remissions prior to adolescence are observed in up to 70% of cases but can re-emerge in some patients. Eczema, often first observed on the scalp, face, or flexure areas of the limbs, is characterized by a relapsing course. Most cases are of mild to moderate involvement, but approximately 10% are severe, involving frequent flares and an extensive lesion burden. Other atopic conditions, such as bronchial asthma and allergic rhinoconjunctivitis, are common in those who develop eczema at an early age. Although infection can complicate eczema, the largest burden of this condition is physical and psychological discomfort.
