What is the term for an inflammation of the skin caused by contact with certain chemicals or substances?

• A. Contact dermatitis
• B. Crust
• C. Cyst
• D. Eczema

Answer: (A)

The term that describes inflammation of the skin triggered by direct contact with specific chemicals or substances is contact dermatitis. This condition occurs when a person's skin reacts to an external irritant or allergen, leading to symptoms such as redness, itching, and swelling in the affected area. It can result from exposure to various agents including soaps, cosmetics, detergents, or plants like poison ivy. In contrast, crust refers to a dried mass of blood, serum, or pus that forms on the surface of the skin, often as a result of healing lesions. A cyst is a closed sac-like structure that can contain liquid, semi-solid material, or gas, and is not inherently inflammatory. Eczema is a broader term that describes a range of chronic skin conditions characterized by inflammation, dryness, and often itching, but is not specifically linked to contact with chemicals or substances like contact dermatitis is.
