Evaluation of minor clinical features of atopic dermatitis.

The diagnostic significance of 19 previously proposed minor features of atopic dermatitis was evaluated. The frequency of these features was studied in 50 patients with typical atopic dermatitis compared to that in 50 control subjects. The ages of all individuals ranged from 3 months to 12 years. Six of the minor features, chelitis, nipple eczema, perifollicular accentuation, white dermographism, recurrent conjunctivitis, and anterior neck folds, were encountered as often in patients as in controls. Two additional features that were of diagnostic significance were diffuse scaling of the scalp and infraauricular fissuring.
