A 13-year-old girl with a history of Crohn disease presented to the pediatric dermatology clinic for evaluation of a rash on her buttocks and back. The patient noticed the rash 1 day prior to presentation. The rash was asymptomatic with no pain or pruritus. Fourteen days prior to presentation, the patient was seen in the emergency department for a temperature greater than 102°F. Since that time, the patient reported low-grade fever and 1 week of headache for which she had been taking ibuprofen. She also reported fatigue. She denied any preceding upper respiratory tract symptoms.
