Angioimmunoblastic lymphadenopathy with dysproteinemia

Three cases of angioimmunoblastic lymphadenopathy with dysproteinemia are reported which illustrate the characteristic clinico-pathological features. These cases also provide information relating to the ultrastructure of the interstitial acidophil material, the histopathological spectrum, where treatment has been attempted, and an incidence figure for an Australian community. Detailed immunological investigations in one case suggest that the disease is a primary B-lymphocyte abnormality.
