[Immunoblastic lymphadenopathy (IBL)-like T cell lymphoma associated with granulocytopenia and autoimmune hemolytic anemia].

: A 65 year-old woman was admitted in May 1990, because of fever, generalized lymphadenopathy and eruption. Laboratory examination showed granulocytopenia, polyclonal hypergammaglobulinemia, positive Coombs' test, positive cold antibody and positive anti-E erythrocyte antibody. 7 days after admission autoimmune hemolytic anemia developed. The appearance of the anti neutrophil leukocyte antibody was suspected because of the absence of the segmented neutrophils in marrow specimen. Histological findings of the biopsied lymph node and the marker study of the tumor cell disclosed IBL-like T cell lymphoma. The patient was treated with G-CSF and VEPA chemotherapy. Granulocytes increased and she showed marked symptomatic improvement with complete remission. Our case showed various clinical pictures with hemolytic anemia and granulocytopenia, which could be based on the autoimmune mechanisms.
