A.

Generalized redness with no scaling

B.

Pustules and fluid-filled blisters

C.

Hyperpigmented patches with rough texture

D.

Thickened, scaly plaques with silvery-white scales

Answer and Explanation

The Correct Answer is D

Explanation: Chronic psoriasis is characterized by thickened, scaly plaques with silvery-white scales. These plaques result from the excessive growth and turnover of skin cells in psoriasis.

Incorrect choices: a. Generalized redness with no scaling: This description does not align with chronic psoriasis. Psoriasis plaques are typically scaly and have a characteristic appearance.

b. Pustules and fluid-filled blisters: Pustular psoriasis is a specific subtype of psoriasis characterized by pustules, but it is not a hallmark of chronic psoriasis.

c. Hyperpigmented patches with rough texture: Hyperpigmentation and rough texture are not typical features of chronic psoriasis. The characteristic feature is the presence of silvery-white scales on thickened plaques.
