Also known as chronic acne, usually occurring in adolescence, with comedones (blackheads), papules (red pimples), nodules (inflamed acne spots), and pustules (small inflamed pus-filled lesions) on the face, neck, and upper part of the trunk.
Acne vulgaris (AV) is a skin disorder seen primarily in adolescents. It is the most common skin disease treated by physicians. AV is characterized by a pilosebaceous follicular eruption of the comedo that starts an inflammatory reaction. A pilosebaceous follicle consists of a follicle or pore, the sebaceous gland, and a hair. These specialized follicles are concentrated on the face, chest, and back. Formation of papules, pustules, and cysts can result from the inflammation. AV is a chronic condition that may last for years and may cause emotional distress and permanent facial scarring. Clinical characteristics of AV vary with age, stage of puberty attained, gender, and race.
