[Malignant histiocytosis with complex chromosomal abnormality: successful treatment with CHOP-E chemotherapy].
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.
