Which skin condition is an allergic inflammation with erythema and itching, non-contagious, caused by various triggers?

• A. Atopic Dermatitis
• B. Psoriasis
• C. Acne Vulgaris
• D. Fungal infection

Answer: (A)

Atopic dermatitis is a chronic inflammatory skin condition driven by allergic-type responses, producing erythema (red patches) and intense itching. It is non-contagious and tends to flare in response to a variety of triggers such as irritants (soaps, detergents), allergens (dust mites, pollen, pet dander), climate, and stress, especially in people with a compromised skin barrier. The skin often appears dry and inflamed, with itch-scratch cycles that can worsen the symptoms. This fits the described scenario better than other choices, which involve distinct patterns: psoriasis shows autoimmune plaques with silvery scales; acne vulgaris centers on clogged pores and pimples; fungal infections are typically contagious and present with ring-shaped or scaly lesions.
