Acne vulgaris, the common type of acne, occurs during puberty and affects the comedogenic areas of the face, back, and chest. There may be a familial tendency to acne.

Adult acne is a variant affecting 1% of men and 5% of women aged 40. Acne keloidalis is a type of scarring acne seen on the neck in men.

These may be associated with inflammatory papules and pustules developing into larger cysts and nodules. Resolving lesions leave inflammatory macules and scarring.

Keloids consist of hypertrophic scar tissue and occur predominantly on the neck, upper back, and shoulders and over the sternum. more…
