You are asked to evaluate a healthy 9-year-old girl with an itchy rash on her face, neck, and hands for a week. She had a similar eruption 1 month ago that resolved over several days. Although she has a history of poison ivy, her parents knew of no exposure. There was no history of new topical skin products. However, she had begun to eat more seasonal fruits recently, including strawberries, grapes, and mangos.
