Severe Raynaud's syndrome associated with interferon therapy. A case history

Side effects of long-term interferon (IFN) therapy for myeloproliferative disorders may be vasospastic Raynaud's attacks and lupus-like illness. The authors report on a woman with chronic myelogenous leukemia who experienced severe trophic lesions of the fingers after forty-nine months of IFN therapy. Digital artery occlusions could be proven arteriographically.
