A 65-year-old Hispanic man with no significant medical history or medication use presented with herpes zoster over the right side of his chest and back involving dermatome T6. The rash, which was the patient's first episode of shingles, had been present for approximately 7 days before presentation. Valacyclovir hydrochloride therapy (1 g 3 times a day for 7 days) was initiated. When the patient returned for follow-up 2 months later, the rash had healed with no scarring, but the hairs in the affected areas on his chest had become white (Figure). He had never had white hairs on his chest before, and he stated that the hairs became white after the herpes zoster resolved. There were no pigmentation changes in the hairs on the affected areas of his back. He had no other symptoms and is doing well.
