Allergic contact dermatitis is a delayed type allergic reaction on the skin after contact to a specific allergen. For allergic contact dermatitis to occur, the skin must first come into contact with the offending agent and sensitization to occur. At first, the area might sting or burn, but then later itch is the major problem. The dermatitis rash might appear as itchy bumps, dry and scaly skin, or thickened darker colored skin.
A qualified Allergy and Immunology specialist can perform patch testing for difficult cases. A patch test will enable the identification of the offending agent. Avoidance of contact with the offending agent is the key to success in allergic contact dermatitis treatment.
