Contact dermatitis
Contact Dermatitis
Contact dermatitis (pronunciation: /kɒnˈtækt dɜːrməˈtaɪtɪs/) is a type of inflammation of the skin that occurs when substances come into contact with the skin and cause an allergic reaction or irritation.
Etymology
The term "contact dermatitis" is derived from the Latin contactus meaning "touch" and the Greek dermatitis meaning "inflammation of the skin".
Types
There are two types of contact dermatitis:
- Irritant contact dermatitis (ICD) is caused by the direct effect of an irritant substance on the skin.
- Allergic contact dermatitis (ACD) is an immune response following skin exposure to an allergen.
Symptoms
Symptoms of contact dermatitis can include itching, redness, swelling, and blistering of the skin. The severity of the reaction can vary depending on the substance and the individual's sensitivity.
Causes
Contact dermatitis can be caused by many different substances, including soap, detergent, cosmetics, nickel, rubber, and certain plants like poison ivy or poison oak.
Treatment
Treatment for contact dermatitis typically involves avoiding the irritant or allergen, using topical steroid creams to reduce inflammation, and taking antihistamines to relieve itching.
