A 47 year-old woman with generalized fresh tense or ruptured bullae was diagnosed as bullaus pemphigoid by histopathological and direct immunofluorescent test. We treated her with prednisolone and bethamethasone for 3 weeks. And soon after, herpes zoster developed along the right T9 dermatome. It is not precise whether true association or only incidental concomitance, but, there may be present some relatioship.
