Acne is a type of which skin lesion?

• A. Pustule
• B. Macule
• C. Vesicle
• D. Nodule

Answer: (A)

Acne is driven by inflammation of a hair follicle with pus formation. A pustule is a small, raised lesion that contains pus in the center, produced by neutrophilic inflammation within the follicle. This pus-filled site is a hallmark of inflammatory acne. By contrast, a macule is flat and non-palpable, a vesicle is a small fluid-filled blister, and a nodule is a larger, deeper, solid bump. So the pustule best matches the typical acne lesion.
