Contact dermatitis is a rash that is brought on either by contact with a specific chemical to which the patient is uniquely allergic or with a substance that directly irritates the skin. Some chemicals are both irritants and allergens. This rash is tends to be weepy and oozy and affects the parts of the skin which have come in direct contact with the offending substance. Common examples of allergic contact dermatitis are poison ivy, poison sumac, poison oak (same chemical, different plant) and reactions to costume jewelry containing nickel.
This is a common type of irritant contact dermatitis that occurs in most infants and some adults who wear diapers when feces and urine are in contact with skin for too long.
This is a weepy, oozy dermatitis that occurs on the lower legs of individuals who have chronic swelling because of poor circulation in veins.
