Minor Clinical Features of Atopic Dermatitis

The diagnostic significance of 8 previously proposed minor features of atopic dermatitis (AD) was evaluated. The minor features studied were: nipple eczema, cheilitis, Dennie-Morgan infraorbital fold, pityriasis alba, anterior neck folds, wool intolerance, white dermographism and infraauricular fissuring. The incidence of these features was appreciated in 105 patients with typical AD (median age 8.5 years) and compared to that in 113 control subjects (median age 16 years). The ages of all studied individuals ranged from 7 months to 24 years. Two of these signs, anterior neck folds and the Dennie-Morgan infraorbital fold as defined by us, were shown to be of no diagnostic significance. The other 6 features were confirmed to be valuable diagnostic clues in AD.
