[QUOTE="madman, post: 210275, member: 13851"] [B]COMMENTARY [/B] [I]Acne vulgaris begins as minute pathological micro comedones.

Furthermore, hypertrophic scars and keloids occasionally occur in acne conglobata [1, 2].[/B] Postinflammatory papule (PIP) is proposed herein as a tentative new designation for acne vulgaris. PIP is defined as brown and dark brown papules that form from red papules and pustules, resulting in postinflammatory hyperpigmentation (PIH) and scarring. [B]We define PIP as a transitional eruption between red papules, pustules, and postinflammatory hyperpigmentation (PIH). When inflammation (manifesting as red papules or pustules) subsides, brown and dark-brown papules remain as PIP. PIP is not a macule, such as a PIH, but a papule.[/B] In PIP, histopathology is necessary to confirm inflammation, noninflammatory infiltration, and scar tissue. To the best of our knowledge, the concept of PIP has not yet been described. However, PIP is usually encountered in acne lesions.
