The association between Kaposi's sarcoma and dysgammaglobulinemia

The case of a patient with Kaposi's sarcoma and paraproteinemia is described and the relevant literature is reviewed. It is suggested that Kaposi's sarcoma is part of the spectrum of the lymphoproliferative diseases, and that both the marked angiogenesis and the synthesis of paraproteins in this disease are different expressions of the same proliferative process.
