While acne primarily affects adolescents, it may also affect adults. There are several phenotypes, one of which is Papulopustular Postadolescent Acne (PPAA).


Clinical features of PPAA:

(1) The lesions are primarily on the lower face, jaw and neck.

(2) The patient has mild-to-moderate inflammatory lesions, primarily deep-seated, tender papules, pustules and nodules.

(3) Comedones are not a prominent component.

(4) Significant scarring may occur.


PPAA may be classified as persistent (continuation of adolescent acne) or late-onset.
