Resolution of hereditary hemorrhagic telangiectasia and anemia with prolonged alpha-interferon therapy for chronic hepatitis C.

Hereditary hemorrhagic telangiectasia is a group of autosomal dominant disorders, characterized by telangiectases that develop in the skin, mucous membranes, and visceral organs. Currently, there is no satisfactory treatment of hereditary hemorrhagic telangiectasia. Interferon has never been used for the treatment of hereditary hemorrhagic telangiectasia. In this case, we report disappearance of hereditary hemorrhagic telangiectasia lesions after 12 months of treatment with interferon-alpha for chronic hepatitis C. Further studies are warranted to evaluate its role and potential use in the treatment of hereditary hemorrhagic telangiectasia.
