Nummular Contact Eczema: Presentation of a Pediatric Case

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.

Allergic Contact Eczema

Abstract Allergic contact eczema is the most common occupational skin disease caused by allergens. Thus far, no research has been conducted in Poland in relation to the development of contact allergies amongst divers resulting from particular diving suit components. A group of 86 divers were examined using allergy patch tests. Standard products of contact allergy diagnostics were used containing 40 allergens.

Nummular Eczema

This review describes eczematous dermatitis, or eczema, a skin disease that is characterized by erythematous vesicular, weeping, and crusting patches; atopic dermatitis, a common chronic inflammatory dermatosis that generally begins in infancy; and the ichthyoses, a group of diseases of cornification that are characterized by excessive scaling. The purpose of this review is to examine the major variants, epidemiology, etiology, diagnosis, differential diagnosis, and treatment of these dermatologic diseases. Figures depict chronic eczematous dermatitis, allergic contact dermatitis to poison ivy, seborrheic dermatitis, nummular eczema, acute eczematous patches, lichenified patches that appear after chronic rubbing of eczematous patches, erythroderma (total body erythema), and marked scaling (acquired ichthyosis). Tables list the diagnostic criteria for atopic dermatitis and the differential diagnosis of atopic dermatitis. This review contains 9 highly rendered figures, 2 tables, and 88 references.
