Abstract

Allergic contact dermatitis is an inflammation of the skin characterized by redness and the formation of vesicles; vesicles are similar to blisters. Allergic contact dermatitis occurs after exposure to a wide variety of substances—many of which are also capable of causing nonallergic irritation. This irritant reaction appears following injury to cells as a result of direct contact with the offending substance; the allergic response develops after repeated contacts with a sensitizer, which eventually provokes an immune inflammatory side reaction in the body. In practice, it is often difficult to distinguish allergic from irritant contact dermatitis. Table 20 lists ways in which they differ.
