title: [CD3-, OKM1+, Leu7-, Leu11+ large granular lymphocyte leukemia with ascites and CNS involvement].
abstract: A case of large granular lymphocyte (LGL) leukemia with ascites and CNS involvement was reported. A 39-year-old Japanese female was admitted to our hospital in March, 1987 because of high fever. Her clinical and hematological features were characterized by generalized lymphadenopathy, marked hepatosplenomegaly, high serum LDH level (3,257 mU/ml), marked leukocytosis (71,000/microliters) with 74% LGLs and bone marrow infiltration with 57% LGLs. Despite of chemotherapy, ascites, retroperitoneal mass and CNS involvement developed and she died of sepsis after three months. LGLs from the patient's blood, marrow and ascites, stained positively for acid phosphatase. These LGLs were E rossete+ and Fc (IgG) receptor+ and were positive for CD2, OKM1, HLA-DR and Leu11, but were negative for CD1, CD3, CD4, CD8 and Leu7 as well as for terminal deoxynucleotidyl transferase activity. The natural killer activity against K562 target cells was high and was significantly augmented after stimulation by recombinant human interleukin 2. These LGLs also demonstrated normal antibody-dependent cytotoxicity activity. Cytogenetic study on bone marrow cells and ascitic cells revealed clonal chromosomal abnormalities. These clinical, hematological, immunological and cytogenetic findings suggest that this patient had a neoplastic proliferation of natural killer cells.
