Acne Vulgaris (Common Acne) and Cystic Acne

Acne is an inflammation of the pilosebaceous units of certain body areas (face and trunk, rarely buttocks) that occurs most frequently in adolescence and manifests itself as comedones (comedonal acne), papulopustules (papulopustular acne), or nodules plus cysts (nodulocystic acne and acne conglobata). Pitted, depressed, or hypertrophic scars may follow all types but especially nodulocystic acne and acne conglobata. Severe acne includes one or more of the following: persistent or recurrent inflammatory nodules, extensive papulopustular lesions, active scarring, and/or presence of sinus tracts.
