Allergic contact dermatitis occurs as a result of a specific skin response to a substance (allergen) to which has previously been sensitized through a mechanism of delayed hypersensitivity type IV. Its appearance occurs in susceptible people, is not predictable, never occurs on the first contact and can affect all the skin.
