An 82-year-old woman was admitted with fever and anorexia. Aggravated pancytopenia and liver dysfunction suggested the presence of disseminated intravascular coagulation. The serum ferritin level increased to 9,100 ng/ml. Bone marrow aspiration showed an increase of histiocytes with phagocytosis and a diagnosis of hemophagocytic syndrome was made. Symptomatic therapy was performed because of her deteriorated general condition. She died of multiple organ failure, 32 days after admission. Autopsy revealed swollen lymph nodes with proliferation of large neoplastic cells containing rich cytoplasm and pleomorphic and multi-segmented large nuclei. The immunophenotype of the neoplastic cells was LCA-, CD3-, CD5-, CD 20-, CD79a-, UCHL1-, MT1-, CD15-, p80-. Neoplastic cells were positive for CD30, mainly in Golgi apparati, and also positive for EBV-encoded small nonpolyadenylated RNAs (EBER). This case was diagnosed as anaplastic large cell lymphoma (ALCL) associated with hemophagocytic syndrome. It was estimated that Epstein-Barr virus had played an important role in the development of ALCL in the present case.

We report an extremely rare case of interdigitating dendritic cell sarcoma/tumor (IDCS). A 52-year-old man presented with a 2-week history of fever in January 2002. Physical examination revealed enlarged, painless right axillary lymph nodes, and hepatosplenomegaly. Whole-body computerized tomography showed enlarged lymph nodes in mediastinal, right axillary, abdominal para-aortic, ileum, and inguinal regions. Hepatosplenomegaly was also detected. In addition to abnormal liver function tests, serum levels of soluble interleukin-2 receptor and ferritin were elevated. Excisional biopsy of right axillary lymph node was performed in February 2002. Histological examination showed a diffuse proliferation of medium-to large-sized cells with round or oval nuclei and abundant cytoplasm. Spindle shape cells and Hodgkin-like giant cells were also seen. Immunohistochemically, the tumor cells expressed S-100 protein, CD 68, and CD 45 RO. They were negative for CD 1, CD 3, CD 15, CD 20, CD 21, CD 23, FDC, DRC, and p80. These findings were compatible with the diagnosis of IDCS. The patient was treated with polychemotherapy consisting of doxorubicin,cyclophosphamide, vincristine, and prednisone. However, he developed fungal pneumonia and died of respiratory failure 1 month after the start of treatment.
