Abstract
The frequency and significance of minor clinical features for the diagnosis of atopic dermatitis (AD) were evaluated in different age‐related subgroups of 100 children (up to 12 yrs) with AD and an equal number of controls. Additional features studied were infraauricular fissuring, diffuse scaling of the scalp, and Hertoghe sign. Features found to be nonspecific were ichthyosis, nipple eczema, cheilitis, keratoconus, anterior subcapsular cataract, pityriasis alba, anterior neck folds, and food intolerance. Other minor features were of variable significance in different age groups. Seasonal variation of AD was observed in 44% of patients, with worsening during winter in 29% and in summer in 15%. Of the additional features, diffuse scaling of the scalp and infraauricular fissuring were significant, but Hertoghe sign was not. It was therefore concluded that minor clinical features for the diagnosis of AD need modification, with deletion of some of the present features and addition of newer ones.
