Although allergic contact dermatitis (CD) was previously thought to occur less frequently in patients with atopic dermatitis (AD), more recent studies show that it is at least as common in patients with AD as in the general population, if not more so. Thus, patients with AD should be considered for patch testing (PT). Although conflicting data exist, the severity of the AD may impact the PT results. ⋯ Hand eczema and compositae allergy are more common in atopic patients. Reassuringly, PT is positive for topical antiseptic and corticosteroids in only a small subset of patients. When personal products are patch tested, emollients should be included in the series.
