[Localized bullous pemphigoid triggered by erysipelas].

Localized bullous pemphigoid is a seldom subtype of bullous pemphigoid. We report the case of a 63-year-old man who developed tense bullae on an erythematous area on the left calf after two episodes of erysipelas. Using histological and direct immunofluorescence studies localized bullous pemphigoid provoked by erysipelas was diagnosed. The patient was successfully treated with topical steroids. Clinicians should be aware of this differential diagnosis to avoid unnecessary antibiotic treatments.
