Disseminated granuloma annulare treated with low-dose chlorambucil

Disseminated granuloma annulare (DGA) is a frequently severe chronic and disfiguring disease that is resistant to conventional methods of therapy. In a patient with DGA, low-dose chlorambucil therapy (2 mg three times daily, orally administered) resulted in dramatic and rapid clearing of all lesions in a short period of time. To my knowledge, this is the fourth case reported in which this therapeutic modality was used.
