Abstract

PESTANA, Letícia; MENDES, Ana; MARQUES, Pedro  and  BARBOSA, Manuel Pereira. Allergy to pacemaker silicone compounds: A new cause of contact dermatitis?. Rev Port Imunoalergologia [online]. 2018, vol.26, n.1, pp.63-66. ISSN 0871-9721.

Although rare, allergic contact dermatitis (ACD) is well described to various components of electrical cardioversion devices. Silicone is a compound described in cases of ACD, such as pacemakers, breast implants or cochlear implants. The location of the lesions usually assists the identification of the agent. However, differential diagnosis with infectious processes is required. The referral to Immunoallergology’s Department allows an adequate investigation, with epicutaneous contact tests, being able to identify the cause and offer safe alternatives. The authors describe a clinical case of suspected contact allergy to implanted cardioverter-defibrillator (CRT-D) components.

Keywords : Allergic contact dermatitis; silicone; pacemaker.
