SIR, Numerous extrahepatic manifestations have been associated with hepatitis C virus (HCV), including vasculitis of small vessels, such as mixed cryoglobulinaemia (MC), and diseases of the larger vessels, such as polyarteritis nodosa (PAN) [1]. There is still discussion about whether HCV is responsible for PAN, but the involvement of this virus in MC is well known [24].
We report three patients with HCV infection and systemic vasculitis who presented with numerous visceral microaneurysms. We discuss the problem of the type of systemic vasculitis (PAN or MC) that is present and the therapeutic consequences. In all patients, tests for antineutrophil cytoplasmic antibodies, HBV and HIV infection were negative.
Patient 1 was a 45-yr-old
