CSS is a multisystem disorder characterized by the triad of asthma, peripheral blood eosinophilia, and vasculitis. Cryoglobulinemia is said to be essential when there is no identifiable underlying disease. Type II and III cryoglobulinemia frequently presents as vasculitis, most commonly with recurrentlower extremity purpura, glomerulonephritis, and peripheral neuropathy. Vasculitis is classified as small vessel, medium vessel or large vessel vasculitis and maybe either idiopathic or associated with an underlying pathology/disease.
