Dermatitis, Allergic Contact () Definition (NCI) An inflammatory skin condition caused by an immune response to direct contact between the skin and an allergen.

      Allergic contact dermatitis occurs when something has come into contact with your skin, which causes your immune system to respond by triggering the activation and production of cells called lymphocytes. They are white cells that produce inflammation in the skin. Allergic contact dermatitis may have acute and chronic forms. Patch testing is a method used to determine if a specific substance causes allergic inflammation of the skin. It tests for delayed reactions. It is used to help ascertain the cause of skin contact allergy, or contact dermatitis. Adhesive patches, usually treated with a number of common allergic chemicals or skin sensitizers, are applied to the Causes: Genetic and environmental factors.

Allergic contact dermatitis is a type 4 or delayed hypersensitivity reaction and occurs 48–72 hours after exposure to the allergen.

How common is contact dermatitis. Contact dermatitis is an inflammatory eczematous skin disease. It is caused by chemicals or metal ions that exert toxic effects without inducing a T-cell response (contact irritants) or by small reactive chemicals that modify proteins and induce innate and adaptive immune responses (contact allergens).[1][2][3][4].

The two types of contact dermatitis are irritant and allergic. Irritant contact dermatitis is produced by a substance that has a direct toxic effect on the skin.

Allergic contact dermatitis triggers an immunologic reaction that causes tissue inflammation. Examples of irritants include acids, alkalis, solvents, and detergents.

These two different forms of contact dermatitis can be difficult to by: What is allergic contact dermatitis.

Irritant contact dermatitis is the most common type of contact dermatitis. It happens when the skin touches an irritating chemical, experiences too much friction, or makes contact with heat.

Although some chemicals are both irritants and allergens, allergic contact dermatitis results from brief contact with substances that don't usually provoke a reaction in most people. The dermatitis usually shows redness, swelling and water blisters, from tiny to large.

The blisters may break, forming crusts and scales. Contact dermatitis arises from a chemical in contact with the skin which may cause either irritant or allergic dermatitis.
