A persistent facial rash.

A 46-year-old woman presented with a facial rash that had worsened over nine months. She had been treated with several topical corticosteroids and topical antibiotics, which improved her symptoms only temporarily. She was taking no other medications. There were no specific triggers or contacts, and she had no significant medical history. Examination revealed annular plaques with a raised erythematous border on the forehead (Figure 1) and both cheeks (Figure 2). Other areas of her body were not affected.
