Answer

Examination in patients with acne vulgaris includes the following features:

  • Comedonal acne: Presence of open and closed comedones but usually no inflammatory papules or nodules

  • Mild acne: Presence of comedones and a few papulopustules

  • Moderate acne: Presence of comedones, inflammatory papules, and pustules; a greater number of lesions are present than in milder inflammatory acne

  • Nodulocystic acne: Presence of comedones, inflammatory lesions, and large nodules greater than 5 mm in diameter; scarring is often evident
