Second only to poison ivy, metal causes the most common form of allergic contact dermatitis, according to a March 24, 2003, news release from the American Academy of Dermatology. In the past, more women have suffered from metal allergy than men, but as increasing numbers of men have started wearing jewelry, their incidence of metal allergy has increased. The trend of body piercing has led to contact dermatitis induced irritation and rashes on earlobes and upper portions of the ear, lips, noses, tongues, navels, breasts, and genitalia.

Symptoms of metal allergy generally occur between six and 24 hours after exposure to the allergen and will dissipate if exposure is eliminated. Symptoms can include redness, swelling, and blisters. This rash normally appears only at the site of contact, although in severe cases, it may extend beyond the contact area. Allergens can be transmitted from fingers to the face, eyelids, or genitals.

The most common metal allergens include

* nickel, which is found in costume jewelry, buttons, and other common metal objects;

* cobalt, which is found in common metal objects, sawdust, seawater, blue pigments, and building materials; and

* chromate, which is found in cement and used as a leather tanning agent.

Individuals who suspect they have a metal allergy should see a dermatologist to determine treatment options.
