Cryoglobulinaemic neuropathy--a clinical spectrum.

In this report we present two cases who illustrate both ends of the spectrum of neuropathy with cryoglobulinaemia. Both patients responded well to treatment. A cryoglobulin assay should be done routinely in patients with mononeuritis multiplex of unknown cause, cutaneous vasculitis with cold sensitivity and chronic demyelinating neuropathies of unknown cause.
