A 27-year-old Caucasian woman came into our clinic with an erythematous, papulopustular rash on her face. The small papules and pustules formed a confluence around her mouth and on her chin; the vermilion border was spared (FIGURE). The patient said that the rash started as a dry scaly patch on the corner of her mouth, and it spread over the course of a few weeks.
The patient had a history of eczema for which she used mometasone furoate cream. Initially, she thought the rash was a flare-up of her eczema, so she used her steroid cream. After using the cream on her face for a month, the patient reported that the rash continued to worsen and spread. She said that the rash was mildly itchy and that when she opened her mouth, it was moderately painful.
