Which lesion is most characteristic of mild acne?

• A. Open comedones
• B. Erythematous papules
• C. Nodules
• D. Cysts

Answer: (A)

Mild acne is dominated by noninflammatory changes in the follicles, mainly clogged pores called comedones. Open comedones, or blackheads, occur when the pore remains open and the plug oxidizes, giving the characteristic dark appearance. This noninflammatory clogging is the hallmark feature of mild acne. In contrast, inflammatory lesions like erythematous papules signal progression to a higher severity, while nodules and cysts are deep, painful lesions associated with more severe acne and a greater risk of scarring. So open comedones best fit the description of mild acne.
