Abstract
BackgroundPhantom limb pain [PLP] may complicate limb amputation. This symptom has been never described in patients with mixed cryoglobulinemia [MC] syndrome.FindingsWe observed three patients with hepatitis-C virus-related MC complicated by severe skin vasculitis responsible for gangrene needing limb amputation. After surgery, they developed refractory PLP and stump pain, which was successfully treated with pregabalin.ConclusionsA clear improvement of PLP was observed in all patients during pregabalin; in addition, this treatment permitted an effective bed preparation and intensive medications of relapsing vasculitic ulcers in the stump, followed by complete resolution of skin lesions. At the same time, traditional analgesic therapies, potentially responsible for relevant side effects, were progressively tapered until discontinuation.
