Cryoglobulinemia
Introduction

Cryoglobulinemia is characterized by intravascular precipitation and obstruction.

Monoclonal cryoglobulinemia is associated with monoclonal proliferation, usually malignant: plasmocytoma (myeloma), immunocytoma and deposits consists of immunoglobulins (IgG, IgM). Inflammation is mild.

Mixed type sometimes accompanies chronic inflammatory diseases (rheumatoid arthritis, lupus erythematosus, hepatitis). Histology is dominated by leukocytoclastic vasculitis. Intravascular deposits are found only rarely.

Both types are characterized by ischemic lesions of acral parts of the body (ulcerations).

In some cases of cryoglobulinemia no primary process can be identified (essential cryoglobulinemia).
