Monoclonal hypergammaglobulinemia without malignant transformation in angioimmunoblastic lymphadenopathy with dysproteinemia.
Overview
abstract
A patient with angioimmunoblastic lymphadenopathy with dysproteinemia had a monoclonal IgG hypergammaglobulinemia. In contrast to previous reports, the development of a monoclonal paraprotein in the setting of angioimmunoblastic lymphadenopathy with dysproteinemia did not herald a transformation to malignancy. The patient improved clinically and the monoclonal gammopathy disappeared when the patient was treated with prednisone. The relationship of these findings to current concepts regarding the cause of angioimmunoblastic lymphadenopathy with dysproteinemia is discussed.
