Allergic skin diseases include atopic dermatitis, contact dermatitis, and urticaria (hives).
Step-by-step explanation:
Allergic skin diseases are a type of hypersensitivity reaction where the immune system overreacts to certain substances in the environment and causes inflammation in the skin. Some examples of allergic skin diseases include:
- Atopic dermatitis: Also known as eczema, it is characterized by itchy, red, and inflamed skin.
- Contact dermatitis: It occurs when the skin comes into contact with an allergen, such as poison ivy, nickel, or latex, and results in a localized rash.
- Urticaria: Commonly known as hives, it presents as itchy, raised, and red welts on the skin.
