Acne Vulgaris

Excerpt

Acne vulgaris is a common cutaneous inflammatory disorder of the pilosebaceous unit, which runs a chronic course. The condition commonly manifests with papules, pustules, or nodules primarily on the face, although it can also affect the upper arms, trunk, and back. The pathogenesis of acne vulgaris involves the interaction of multiple factors that ultimately lead to the formation of its primary lesion, which is known as "comedo" (see Image. Acne Vulgaris). Although acne vulgaris is commonly observed among adolescents, it is not restricted to this age group and can affect individuals of various ages. The severity of this condition can vary, ranging from a mild presentation with only a few comedones to more severe forms characterized by disfiguring inflammatory manifestations, which can lead to hyperpigmentation, scarring, and adverse psychological effects.
