Perioral dermatitis is an acne-like problem that usually affects young women and causes small papules on the chin, around the mouth, and along the jawline.
Some of these papules may be deep-seated, but this usually does not cause the large, scarring nodules and cysts of true acne.
Cystic acne may also be part of a syndrome that also involves some combination of acne on the face with draining lesions and boils of the scalp (dissecting cellulitis of the scalp), axilla (hidradenitis suppurativa), groin, or chest.
Conglobate acne is a severe form that may present as a severe cystic acne of the face and trunk, which can also have systemic manifestations such as arthritis and other musculoskeletal problems.
Cystic acne is a form of acne associated with long-standing, painful nodules of the face, back of neck, chest, and back.
This form of acne is likely to result in permanent scarring. Most patients with cystic acne require aggressive medical therapy to prevent blemishes.It starts with closed comedos (whiteheads), which may progress to open comedos (blackheads).Unless they are picked, popped, and manipulated, these would only rarely cause scarring.As these are space-occupying collections of inflammatory material, scarring is predictable.
Cystic acne may involve the face, chest, back, or unique combinations of these.
There is a trend that if a parent or older sibling had significant scarring acne, you are more likely to develop it yourself.
