Although lesions of perioral dermatitis may burn or feel tender, most patients complain about their appearance rather than about specific symptoms. The disease is more common in women and usually occurs in early adulthood (25 to 35 years of age). Erythematous papules and pustules with minimal scales are the characteristic lesions (Fig. 10-1). This condition may be worsened by fluorinated topical corticosteroids or by fluorinated tartar control toothpastes.
