In the past few years, synthetic sport shorts, used for sports, swimming, or everyday wear, have become popular because of their quick-drying, lightweight, and rip-proof features. Usually made of all nylon or other synthetics, sport shorts are manufactured using various chemicals (dyes, resins, formaldehyde, and other compounds) that may cause dermatologie reactions. As described below, such shorts can present a problem for their wearers.
Patient Report. An otherwise healthy 7-year-old boy presented with a 3-day history of rash noted only on his thighs. His medical history was unremarkable; he was receiving no medications and had no known drug or other allergies. The rash had developed over a 3-day period during which he had worn synthetic shorts to soccer camp. The weather had been excessively hot (above 35°C) and he had been very active. The patient noted that the loose-fitting shorts occasionally "stuck to his legs" during the day.
