RESUMEN
La Dermatitis de Contacto secundaria a metales tiene una alta prevalencia en Chile y el mundo, sin embargo estas reacciones han sido poco estudiadas, pese a que podrían verse hasta en un21 por ciento de personas previamente sensibilizadas. Níquel, Cobalto y Cromo son los metales mayormente implicados. La mayoría corresponde a reacciones eccematosas. Test de parche es el gold standard para el estudio de alergia a metales, no obstante, rara vez se utiliza debido principalmente al bajo índice de sospecha de estas reacciones y a la dificultad para disponer de la aleación exacta del metal utilizado. El tratamiento muchas veces consiste en retirar el implante, puesto que el cuadro se torna inmanejable. Se presenta un caso clínico altamente sospechoso de alergia a implantes metálicos, al que se le realizó el estudio completo de alergia a metales, si bien esta no se demostró. Se realiza una revisión de la literatura existente.
ABSTRACT
Contact dermatitis secondary to metals has a high prevalence in Chile and around the world. Nevertheless, these reactions have been slightly studied, even though they might be found inpreviously sensitized people, with a percentage of 21 percent. Nickel, cobalt and chromium are the most involved metals. The majority of them correspond to eczematous reactions. Patch test is the gold standard for the study of metal allergies; however, specific tests to the implant material are rarely performed, mainly because of the low index of suspicion for these reactions and the difficulty to have the exact alloy of the metal used. Treatment often consists on removing the implant, since the situation becomes unmanageable. A highly suspicious clinical case of allergy to metallic implants is presented, a complete study of allergy to metals was made, although it couldnt be demonstrated. A review of the existing literature was conducted.
