For 6 years, a 32-year-old man had a recurring rash on his back, shoulders, and chest. He stated that the rash appears in the spring, itches, and enlarges into ringlike areas. Previously, when treated with cephalexin, the rash had cleared within several weeks. Antifungal medication (econazole cream and oral terbinafine) had failed to resolve the rash.
