Vulvar skin disorders include a variety of inflammatory conditions of the vulva that also may affect the extragenital area. Pruritus and pain are two of the most common presenting symptoms in vulvar clinics (1). Vulvovaginal symptoms often are chronic and can adversely affect sexual function and sense of well-being. The purpose of this Practice Bulletin is to provide updated diagnostic and management recommendations for the most common vulvar skin conditions associated with inflammation: contact dermatitis, lichen simplex chronicus, lichen sclerosus, and lichen planus. Other vulvovaginal disorders such as vaginitis, vulvar low-grade squamous intraepithelial lesions and vulvar high-grade squamous intraepithelial lesions (previously termed vulvar intraepithelial neoplasia), genitourinary syndrome of menopause (vulvovaginal atrophy), and vulvar pain (vulvodynia) are addressed in other documents from the American College of Obstetricians and Gynecologists (2–6).
