Diagnostic quiz: persistent redness & inflammatory flares
A 30-year-old woman makes an appointment to see a dermatologist for the first time. The patient is worried about a persistent redness on her nose and upper and lower cheeks that will not go away. At first, the patient thought the redness was related to repeated exposure to the sun, but the redness has lingered and worsened even after using sunscreen and trying a variety of over-the-counter lotions. After asking about the patient’s history, the dermatologist has learned that in the past, the patient had experienced flares of what she thought was mild acne with some inflammatory papules and pustules and accompanying erythema, but she has not had a flare for a few years and thought she was past the condition.
