[Diffuse B-cell lymphoma associated with hemophagocytic syndrome].

An 84-year-old female was admitted to our hospital because of fever. Physical examination and computed tomography revealed hepatosplenomegaly without lymphadenopathy. Anemia and thrombocytopenia were noted and the serum levels of LDH, IL-6 and sIL-2R were elevated. Bone marrow aspiration showed infiltration of lymphoma cells and proliferation of histiocytes with hemophagocytosis. Southern blot analyses revealed rearrangements of both IgJH and IgJK genes. She received corticosteroids with improvement of her general state but she died on the 110th hospital day. Necropsy of the spleen showed diffusely proliferating large lymphoma cells, immunoreactive for B cell marker L-26, and scattered histiocytes with hemophagocytosis.
