Granulomatous vasculitis associated with herpes virus: a persistent, painful, postherpetic papular eruption.

Cutaneous granulomatous vasculitis manifesting as a postherpetic reaction pattern is uncommon hand has previously been reported as a delayed complication of varicella-zoster virus infection. We describe three patients who had persistent, painful, postherpetic papules in a zosteriform distribution that histologically demonstrated a small vessel granulomatous vasculitis. Herpes simplex virus DNA detected by the polymerase chain reaction technique was demonstrated in two cases.
