Which symptom is typical of contact dermatitis?

• A. A persistent dry skin
• B. A red, itchy rash
• C. White patches on the skin
• D. Thickened hair follicles

Answer: (B)

A red, itchy rash is a hallmark symptom of contact dermatitis. This condition occurs when the skin reacts to a foreign substance, leading to inflammation. The rash may appear shortly after exposure to the irritant or allergen and can range in severity. The redness and itchiness signify an immune response and irritation, often accompanied by swelling and sometimes blisters. In contrast, other symptoms listed do not typically align with contact dermatitis. A persistent dry skin can occur due to various skin conditions but is not specifically tied to contact dermatitis, which usually involves an acute response rather than chronic dryness. White patches on the skin may suggest conditions like vitiligo or fungal infections, which are distinct from the inflammatory response associated with contact dermatitis. Thickened hair follicles are often indicative of conditions affecting hair growth or blockage but don't describe the primary reaction seen in contact dermatitis.
