An example condition commonly associated with plaques is:

• A. Acne
• B. Psoriasis
• C. Chicken pox
• D. Basal cell carcinoma

Answer: (B)

Plaques are flat-topped, raised skin lesions larger than about 1 cm. The condition most characteristically associated with plaque-type skin lesions is psoriasis, particularly plaque psoriasis. It presents as well-demarcated red plaques with silvery scales on commonly affected areas like the elbows, knees, and scalp. The reason this is the best choice is that the hallmark of psoriasis is these thickened, scaly plaques resulting from autoimmune-driven keratinocyte hyperproliferation and inflammation, leading to rapid skin turnover and scaling. Acne features comedones and inflammatory papules or nodules rather than broad, flat plaques. Chickenpox presents with vesicular lesions in various stages that crust over, not classic plaques. Basal cell carcinoma often appears as a pearly papule or nodule with telangiectasia; while some variants can look plaque-like, the classic association for plaque-type skin lesions is psoriasis.
