Generalized granuloma annulare and hepatitis B vaccination.

As hepatitis B vaccination is becoming generalized in Europe, cutaneous adverse events are being more frequently reported in the literature. We report the first case of generalized granuloma annulare following hepatitis B immunization. A 51-year-old woman presented a generalized granuloma annulare one month after the one-year booster injection of the hepatitis B vaccine. The lesions resolved with sulfone therapy. We observed an identical recurrence three weeks after the five-year booster.
