Immunoblastic lymphadenopathy is a recently described lymphoproliferative disorder, presumably of B-cell origin. It is characterized by regional or generalized lymphadenopathy, usually associated with hypergammaglobulinemia or dysproteinemia. Other findings may be hepatosplenomegaly, dermatitis, fever, malaise, weight loss, and various altered immunologic reactions. Histologically, the involved lymph nodes show immunoblast, plasmacytoid, and plasma cell proliferation. This may be extranodal as well. The case reported here is one of the few followed up prospectively. The patient's purpuric eruption was an apparent manifestation of a type II mixed cryoglobulinemia. Differing from what has usually been reported, we noted hypogammaglobulinemia and findings in part of altered cell-mediated immunity. Despite leukopenia and anemia there were no infectious episodes. Although a satisfactory treatment regimen has not been established, there was beneficial response to prednisone and short courses of melphalan.

An 88-year-old woman was admitted with generalized lymphadenopathy, anemia, and thrombocytopenia. On admission, a peripheral blood examination showed a red blood cell count of 146 x 10(6)/microliter, a hemoglobin concentration of 6.9 g/dl, and a platelet count of 5.0 x 10(4)/microliter. Blood examination detected polyclonal hypergammaglobulinemia; the results of the direct/indirect Coombs' test were positive; and an elevated cold agglutinin titer and high platelet associated IgG (PA-IgG) level indicated the existence of autoantibodies. Serum cytokine measurements disclosed an elevated level of interleukin-6 (IL-6). Immunoblastic lymphadenopathy-like T cell lymphoma was diagnosed on the basis of lymph node biopsy specimens. VP-16 and steroid therapy alleviated the patient's lymphadenopathy, anemia, thrombocytopenia, and hypergammaglobulinemia. These findings suggest that tumor cells with a T cell phenotype produced IL-6 in large quantities, thus provoking B-cell and plasmacytic histologic changes and humoral disease manifestations, including hypergammaglobulinemia.
