Las resinas epoxi son plásticos muy empleados como aislantes eléctricos, en recubrimientos y como adhesivos y pinturas. Presentan un gran poder sensibilizante y son una de las principales causas de eczema alérgico de contacto, tanto en el medio laboral como fuera de éste. Presentamos el caso de un trabajador de una planta plastoquímica que manipulaba componentes de material aeronáutico en el proceso de fabricación de piezas de fuselaje. Consultó por lesiones eczematosas en los dedos, manos y antebrazos, de 2 años de evolución, en clara relación con su actividad laboral. Se realizaron pruebas epicutáneas con la batería estándar, la de plásticos y adhesivos y sus productos propios. Se objetivaron positividades a resinas epoxi (batería estándar) y a sus productos propios, entre los que se encontraban distintas láminas de fibras de vidrio y carbono impregnadas con resinas epoxi y adhesivos epoxi
Epoxy resins are plastics that are widely used as electrical insulation, in coatings, and as adhesives and paints. They have strong sensitizing power and are one of the main causes of allergic contact eczema, both in the workplace and elsewhere. We present the case of a worker at a plastics/ chemical plant, who handled aeronautical components in the process of manufacturing fuselage parts. He consulted his physician because of eczematous lesions on his fingers, hands and forearms which had developed over a two-year period and were clearly related to his work. The standard battery of skin tests was performed, along with the plastics and adhesives series and tests using the products from his workplace. Positivity was shown to epoxy resins (standard battery) and to the products from his workplace, which included different fiberglass and carbon fiber sheets impregnated with epoxy resins and epoxy adhesives
