Resumen
PAUTT-LARA,, Evelia; CALA-CASTRO,, Laura; HARRIS, Olga y VILLARINHO, Ana Luiza. Late-onset atopic dermatitis with nummular pattern. Rev. alerg. Méx. [online]. 2019, vol.66, n.4, pp.483-487. Epub 25-Sep-2020. ISSN 2448-9190. https://doi.org/10.29262/ram.v66i4.552.
Background:
Adults with atopic dermatitis have had a persistent form in childhood or with an onset after the age of eighteen years. Late-onset atopic dermatitis may present with clinical heterogeneity and it often lacks the classic pattern of flexural dermatitis.
Clinical case:
A 26-year-old man with allergic rhinitis, with late-onset eczema, and an atypical nummular pattern on his trunk and limbs. The skin biopsy showed eczema-like lesions which, together with the patient’s personal history and laboratory abnormalities, allowed the diagnosis of the adult’s late-onset atopic dermatitis. Treatment with methotrexate was started and there was no response, which is why phototherapy was prescribed due to the dependence on systemic corticosteroids.
Conclusion:
Atypical presentations of atopic dermatitis in adults represent a clinical challenge. A personal history of atopy, sensitivity to aeroallergens, eosinophilia, and a cutaneous biopsy are essential to establish the diagnosis.
