Abstract

The etiopathogenesis of the nummular eczema is not fully known. Various causative factors have been proposed, and among these only a few studies investigate the relevance of contact allergy. Here, we present a case of nummular contact eczema in an 8-year-old allergic to perfumes. Since atopic dermatitis may also present with different clinical phenotypes, among which nummular eczema is quite frequent, the possible significant differences between non-atopic and atopic nummular diseases are considered. Based on the high incidence of contact sensitization in all cases of nummular eczema, it is recommended to perform patch tests for diagnostic-preventive purposes.
