Which term refers to a noninfectious inflammatory skin condition often presenting with itching and redness?

• A. Eczema
• B. Dermatitis
• C. Folliculitis
• D. Acne Vulgaris

Answer: (A)

Eczema describes a noninfectious inflammatory skin condition that typically shows up as itchy, red patches. It’s commonly used to refer to atopic dermatitis, a form of dermatitis driven by immune activity and skin barrier dysfunction, which is why itching is a hallmark feature. Dermatitis is a broader term for skin inflammation and can refer to many different causes, including irritants or allergies; it isn’t as specific to the classic itchy, red presentation. Folliculitis involves infection of hair follicles and often has pustules and tenderness, not just itching and redness. Acne vulgaris centers on clogged pores with pimples and comedones, and isn’t primarily about diffuse itchy red inflammation. So the term that best fits the described noninfectious, itchy, red skin condition is eczema.
