title: [Mixed cryoglobulinemia with necrotizing angiitis. Apropos of 2 cases].
abstract: Out of a series of 26 personal cases, 2 cases of mixed IgM-IgG cryoglobulinemia, one type II the other type III, are reported because they were associated with histologically proven necrotizing vasculitis. In both cases the numerous symptoms were due to renal damage (the vasculitis was discovered in the kidney) and to peripheral neuropathy. One of the patients died; the other had severely deteriorated general condition and required substitution hemodialysis. Cases of vasculitis associated with mixed cryoglobulinemia have often been published, but there are few reports mentioning necrotizing vasculitis; a search in the literature yielded only 9 cases. This small number does not mean that mixed cryoglobulinemia should not be listed among the causes of necrotizing vasculitis, but it makes it difficult to extract those specific features that would enable to predict which case of mixed cryoglobulinemia is associated or not with necrotizing vasculitis.
