A 43 year-old man admitted to our hospital because of fever and splenomegaly. Laboratory findings were as follows: Hb 9.5 g/dl, Plts 4.9 X 10(4)/microliter, LDH 2,348 IU/l. Bone marrow findings showed tumor cell 47% with or without phagocytosis. The tumor cells were stained positive lysozyme and alpha 1 antitrypsin. Cytogenetic study was 47, XY, -7, -8, +9, -11, -12, -19, -21, 3q+, 6p+, +6 markers. This case was diagnosed as malignant histiocytosis. Complete remission was achieved with CHOP-E chemotherapy. Remission has been maintained with repeated this therapy. Etoposide deserves a good evaluation in the treatment of malignant histiocytosis. Some cases of malignant histiocytosis with a t(2; 5) (p23; q35) translocation were often reported in Europe and America, while there was no specific chromosomal abnormalities with malignant histiocytosis in Japan.

A 68 year-old-man was first found to have CLL with IgG, kappa monoclonal gammopathy 6 years ago. Bestrabucil (total dose 35,150 mg) was taken orally from August 1989 to December 1989. Etoposide (total dose 23,100 mg) was then orally administered from January 1990 to December 1995. He was then referred to our hospital in January 1996 because of progressive anemia and thrombocytopenia. Peripheral blood showed a WBC of 21,200/microliter with 4% myeloblasts and 79% lymphocytes, Hb 7.9 g/dl and Plt 5 x 10(4)/microliter. The serum level of lysozyme was increased (75.6 micrograms/ml). Bone marrow aspiration disclosed hyper-cellularity with proliferation of the blasts and a monocytoid cell population, which cytochemical studies demonstrated to be of the myelo-monocytic series, thus indicating acute myelogenous leukemia (AML-M4) superimposed on CLL. Surface marker analysis of bone marrow mononuclear cells revealed reactivity for CD 11c, CD13, CD15, CD33, HLA-DR. The karyotype was normal. Southern blot analysis and reverse transcriptase-polymerase chain reaction did not reveal rearrangement of the MLL gene. Complete remission was achieved by chemotherapy consisted of BHAC, idarubicine, 6MP, vincristine and predonisolone. Long-term treatment with oral etoposide may contribute to secondary AML.
