A 2-year-old boy brought for pediatric dermatology consultation because of the "worst diaper rash in the world." Mother reported that the rash had been present for a year and was asymptomatic. She had been using topical barrier creams, corticosteroids, and antifungals to treat the area. Child had also received a course of oral antibiotics. Occasional improvement of rash noted but never complete resolution. Patient had no other medical problems. Family history noncontributory.
