• A. Psoriasis – Incorrect: Psoriasis typically presents with well-demarcated plaques covered by silvery scales, rather than severe dryness with fissuring and intense itching.
• B. Atopic dermatitis – Correct: The combination of dry, itchy, inflamed skin with excoriations and bleeding is classic for atopic dermatitis.
• C. Diaper rash – Incorrect: Diaper rash occurs in infants and is limited to the diaper area, often associated with moisture and irritation.
• D. Acne – Incorrect: Acne presents with comedones, papules, pustules, or nodules, not diffuse dry, inflamed, itchy skin.
