[Nummular dermatitis: report of two cases in children].

Nummular eczema or dermatitis is an uncommon paediatric pathology. It is presented as red-purplish small papules and vesicles that join to form exudative circular patches and then to eczematous or lichenified patches with discoid shape. The lesions appear predominantly on the extensor surface of extremities, although they can appear in trunk, hands or feet. This pathology has a clinical diagnosis; only few cases require complementary test. The topical corticosteroids are the mainstay of the treatment, and the causal treatment whether an infectious trigger is found. The patients have chronic or recurrent evolution. We report two cases in children with the aim of spreading knowledge among pediatricians. Sociedad Argentina de Pediatría.
