A 5-year-old girl presented to our dermatology clinic at Oregon Health and Science University for consultation regarding erythema and edema of the right ear. She was otherwise healthy. Her mother had first noted the right superior helix to be "red and swollen" 4 months before. At that point, her primary care provider had treated her with antibiotic eardrops for suspected otitis externa, without improvement. The otolaryngology service next evaluated her and treated her with a 10-day course of prednisone and cephalexin. She had no response to this treatment either. Over the ensuing months, the affected area extended to involve the entire helix and earlobe. The area was initially tender but became asymptomatic after the first month. She had no other symptoms, specifically, no fever, weight loss, arthralgia, myalgia, or other cutaneous lesions.
