Red fingers syndrome and recurrent panniculitis in a patient with chronic hepatitis C.

Cases of red fingers syndrome and nodular vasculitis in patients with hepatitis C have rarely been described. Both red fingers syndrome and nodular vasculitis are characterized by microscopic vasculitis, and it has been hypothesized that hepatitis C plays a role in the pathogenesis of cutaneous disorders such as vasculitis, especially in cryoglobulinaemic vasculitis. We describe the case of a 75-year-old woman diagnosed with chronic hepatitis C who presented with nodular lesions on her right thigh and red fingers syndrome. A skin biopsy taken from a nodule showed infiltration of the vessel walls by mononuclear cells and septal and lobular panniculitis. The diagnosis of nodular vasculitis was established. In our opinion, red fingers syndrome and nodular vasculitis might be related to a vascular reaction of immune-mediated mechanisms induced by hepatitis C.
