An eczematous eruption in the superior retroauricular areas of the scalp and often on the posterior aspects of the pinnas may be seen in about 30% of allergic children. The eruption is not generally noticed because the overhanging hair covers the affected areas. The dermatitis is seen mainly in those children afflicted with bronchial asthma, perennial allergic rhinitis, or both. A previous history of atopic or seborrheic dermatitis is, as a rule, not elicited.
