Despite its proximity to her eye, she had no ocular involvement and no blurring of vision.This was the rash of herpes zoster. The patient’s herpes virus titer was elevated; she responded well to acyclovir. Also of interest in this case are the 3 lesions on this patient’s forehead (B). These are classic umbilicated papules, of molluscum contagiosum which are not to be confused with herpetic vesicles. (A).(B).
