Which chronic skin condition produces red lesions with silvery scales?

• A. Psoriasis
• B. Rosacea
• C. Ringworm
• D. Impetigo

Answer: (A)

Red lesions with silvery scales point to psoriasis, a chronic autoimmune skin condition where skin cells multiply too quickly, creating thick, red patches covered with a flaky silver-white buildup. This pattern is typical and long-lasting, often appearing on elbows, knees, and the scalp. Rosacea causes persistent facial redness and visible blood vessels without the silvery scales. Ringworm forms ring-shaped lesions with a scaly border and itching rather than silvery plaques. Impetigo produces honey-colored crusts around the mouth and nose, not silvery scales. So the described presentation best fits psoriasis.
