Perioral Dermatitis
摘要
Perioral (aka periorificial) dermatitis is an acneiform inflammatory eruption of the face that has been associated with a variety of triggers, including topical steroids; inhaled steroids used for allergic rhinitis or asthma; toothpastes containing cinnamon, mint, or fluoride; chewing gums; and some sunscreens. A large number of other putative causes include infectious agents like Demodex, cosmetics, hormones, and systemic steroids.
