Which type of dermatitis results from a direct cytotoxic effect of a chemical or physical agent?

Irritant Contact Dermatitis
Allergic Contact Dermatitis
Contact Urticaria
Skin Infections

The correct answer is: Irritant Contact Dermatitis

Irritant Contact Dermatitis occurs when the skin is exposed to a chemical or physical agent that causes direct damage to the skin cells. This can often lead to red, itchy, and inflamed skin. Allergic Contact Dermatitis, on the other hand, results from an allergic reaction to certain substances, rather than direct damage. Contact Urticaria is a type of allergic reaction that occurs immediately upon contact with a substance, often resulting in hives or inflammation. Skin infections, such as bacterial or fungal infections, are not types of dermatitis and can be caused by a variety of factors unrelated to direct cytotoxic effects of chemicals or physical agents. Therefore, the best answer choice for this question is A Irritant Contact Dermatitis.
