It has been suggested that in nickel allergic people pompholyx may be due to nickel in the diet. Sometimes it is due to contact with metal items containing nickel, but often there is no obvious reason for it. It is usually a blistering type of eczema, known as pompholyx or dyshidrotic hand dermatitis. Some people develop intermittent or persistent eczema on their hands and feet. Can nickel allergy affect areas that are not in contact with metal? Some people develop dermatitis from even brief contact with nickel-containing items, while others break out only after many years of skin contact with nickel. Nickel allergy is more common in women, probably because they are more likely to have piercings than men, although this is changing. Once this nickel allergy has developed, it persists for many years, often life-long. Who is affected by nickel allergy?Ĭontact allergic dermatitis to nickel may develop at any age and in males and females. Nickel was declared the Contact Allergen of the Year for 2008 by the American Contact Dermatitis Society (ACDS).
