What does the term contact dermatitis refer to?

• A. An allergic reaction
• B. An inflammation caused by chemicals
• C. A fungal infection
• D. A viral infection

Answer: (B)

Contact dermatitis refers to an inflammation of the skin that occurs when it comes into contact with certain substances, leading to irritation or an allergic reaction. It is often a result of exposure to irritants or allergens, which can include chemicals, plants, metals, or other materials that trigger a skin reaction. In the case of contact dermatitis caused by chemicals, these substances can penetrate the skin's barrier and lead to inflammation, redness, and discomfort. It's crucial to identify the source of the dermatitis in order to prevent further exposure and treat the skin effectively. While an allergic reaction can be a form of contact dermatitis, the term specifically encompasses any inflammatory response triggered by contact with irritants or allergens, making the mention of chemicals particularly pertinent. Fungal and viral infections, on the other hand, pertain to different pathological processes and do not fall under the category implied by the term contact dermatitis.
