Remote abscess formation during interferon-alpha therapy for viral hepatitis.

Abscess formation at the injection site is an unusual infectious complication of interferon-alpha (IFN-alpha) treatment of chronic hepatitis C virus (HCV) infection, but remote abscess formation during IFN-alpha therapy is very rare.
