[Cutaneous manifestations of paraproteinemia and their mechanisms].
Disease entities characterized by the presence of paraproteins have a variety of cutaneous manifestations. These manifestations may be classified in the following categories as a function of their mechanisms: * extracutaneous deposition of paraproteins, as in amyloidosis * intravascular paraprotein deposition, as in cryoglobulinemia * cutaneous lesions resulting from the biologic activity of paraprotein, as in patients with normolipemic xanthoma with monoclonal immunoglobulin anti-LDL activity * abnormal cytokine secretion, as in AESOP (adenopathy and extensive skin patch overlying a plasmacytoma) or POEMS (polyneuropathy, organomegaly, endocrinopathy, monoclonal protein, and skin changes) syndromes * unknown mechanisms.
