Match the lesion type to its best example.

• A. Plaque — Acne
• B. Nodule — Nevi, basal cell carcinoma
• C. Pustule — Burn/blister
• D. Vesicle — Psoriasis

Answer: (B)

A nodule is a solid, raised lesion that extends into the dermis or deeper and is usually larger than a papule. Nevi (moles) and basal cell carcinoma commonly present as discrete, palpable nodules, making them the clearest example of this lesion type.

A plaque is a broad, flat-topped elevation; acne lesions are typically papules and pustules rather than a single plaque, so they don’t serve as the best example of a plaque.

A pustule is a small, pus-filled elevation; burns or blisters involve fluid-filled spaces (vesicles or bullae) rather than pus-filled lesions, so pustules aren’t the best fit there.

A vesicle is a small fluid-filled blister; psoriasis tends to form thick, scaly plaques rather than vesicles, so vesicles aren’t the typical description for psoriasis.

Thus, nodules best map to nevi and basal cell carcinoma.
