Acne lesions are primarily which type?

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

Answer: (B)

Classifying acne by the type of skin lesion is what's being tested here. In acne, inflammatory lesions that contain pus are common, and that pus-filled, raised appearance is what defines a pustule. A pustule results from the follicle becoming inflamed and neutrophils accumulating to form purulent material, giving a small, yellowish or white center with surrounding redness. The other choices don’t fit as well: a macule is a flat color change with no elevation or pus; a vesicle is a small fluid-filled blister; a nodule is a deeper, larger solid bump. Among the options, the pustule best matches the typical inflammatory lesion you see in acne.
