  • Title: [Angioimmunoblastic T-cell lymphoma associated with hemophagocytic syndrome at onset and relapse].
    Author: Takai K, Sanada M.
    Journal: Rinsho Ketsueki; 2000 Dec; 41(12):1260-6. PubMed ID: 11201151.
    Abstract:
    A 66-year-old woman was admitted with high fever, systemic lymphadenopathy, hepatosplenomegaly and pancytopenia. Bone marrow aspiration showed infiltration of atypical lymphoid cells and hemophagocytic histiocytes. The findings of lymph node biopsy were compatible with angioimmunoblastic T-cell lymphoma (AILD). A diagnosis of lymphoma-associated hemophagocytic syndrome (LAHS) was made. Treatment with the THP-COP regimen achieved clinical remission except for mild splenomegaly, but relapse of LAHS was confirmed two years after diagnosis. The patient's condition deteriorated rapidly, and she died of multi-organ failure one month later. Autopsy revealed extended, diffuse infiltration of lymphoma cells in almost all organs. Numerous macrophages showing phagocytosis of erythrocytes and nucleated cells were found in the adrenal glands, lungs, bone marrow, spleen and liver. Epstein-Barr virus genomes were not detected by in situ hybridization, but cytotoxic molecules were immunostained with TIA-1 and granzyme B in the lymphoma cells. Elevated serum levels of sIL-2R, IFN-gamma, IL-6 and M-CSF were found at the onset and relapse of lymphoma. Overproduction of these cytokines was considered to have contributed to the pathogenesis of HPS.
