Use of intravenous immunoglobulin in livedo vasculitis.

We describe a 36-year-old woman with livedo vasculitis (atrophie blanche) lasting for 15 years. After the failure of numerous therapeutic modalities the patient was treated with intravenous immunoglobulin. Significant resolution of the cutaneous lesions was seen with a concomitant alleviation of pain. To the best of our knowledge this is the first patient with livedo vasculitis described in the medical literature ever to be treated with IVIG and to achieve a successful outcome.
