A 5-year-old boy had developed an itchy rash on his trunk at the age of 18 months. This waxed and waned over the next 3 years and gradually came to involve predominantly his flanks, popliteal and anticubital fossae. He had mild asthma requiring occasional bronchodilators only. His mild atopic eczema was treated with bland emollient creams and occasionally 1% hydrocortisone. His prognosis is good and his skin problems are likely to resolve over the next few years.
