Postinflammatory hyperpigmentation (PIH) is an acquired hypermelanosis occurring after cutaneous inflammation or injury that can affect all skin types but more in dark-skinned patients. Etiologies for facial PIH include infections, allergic reactions, papulosquamous diseases such as psoriasis or lichen planus, medication-induced hypersensitivity reactions, and cutaneous injury from irritants, burns, or cosmetic procedures. PIH results from the melanocyte's response to the cutaneous insult causing increased production and/or redistribution of melanin. Literature search could show that this is the first case report on isolated acute perioral PIH following perioral contact dermatitis.
