title: Polyclonal gammopathy with beta-globulin-gamma-globulin bridging. Two unusual cases.
abstract: Polyclonal gammopathy with beta-globulin-gamma-globulin (beta-gamma) bridging has been classically, though not exclusively, described with cirrhosis. We studied two unusual cases that exhibited polyclonal gammopathy with beta-gamma bridging. In the first case, the coexistence of Kaposi's sarcoma appeared with angioimmunoblastic lymphadenopathy. In the second, liver disease developed as a complication of alpha 1-antitrypsin deficiency and retroperitoneal malignant fibrous histiocytoma involving the porta hepatis.
