An 80-year-old male was admitted because of dizziness and palpitation. Laboratory investigation revealed pancytopenia. A bone marrow aspirate showed a markedly hypocellular marrow with 41.6% blast cells. Peroxidase activity was negative and PAS reaction was block positive in the blast cells. Surface markers of these cells were positive for HLA-DR antigen and partially positive for CD13 (MY7). Other markers, such as T, B or myeloid antigens were all negative. These blast cells were classified as L1 according to the FAB system but suggested essentially unclassifiable in cell differentiation. The patient was treated successfully with vincristine and prednisolone and induced into complete remission although repeated marrow examination findings revealed hypocellular. As for the classification of hypoplastic leukemia, lymphoid or primitive "stem cell" leukemia also should be considered as other categories of acute leukemias and be treated according to each case.

A 59-year-old man was admitted to our hospital on May 17, 1991 because of dizziness and a sense of abdominal fullness. Physical examination on admission showed splenomegaly without hepatomegaly or lymphadenopathy, and blood examination revealed normocytic anemia, thrombocytopenia and marked leukocytosis of 16,800/microliters with 87% lymphoid cells. Prolymphocytoid cells formed 28% of the lymphoid cells. Bone marrow aspiration revealed massive infiltration of lymphoid cells. Surface marker analysis showed that the lymphoid cells were positive for anti-HLA-DR, CD 5, CD19, CD20, CD21, SmIgM and SmIgD. The patient was diagnosed as having B-CLL/PL, according to the classification advocated by Melo in 1986, and initially treated with vindesine + prednisolone + pirarubicin (VP-THP). However, the prolymphocyte count increased, so we changed to VP-THP + cyclophosphamide (VEP-THP), and remission was obtained. CLL/PL is a rare disease in Japan but we obtained a good response to chemotherapy.

The t(16;21)(q24;q22), a rare chromosomal translocation involving chromosome 21 in de novo and therapy-related acute myeloid leukemia (AML), produces a RUNX1-CBFA2T3 fusion gene (previously AML1-MTG16) fusion gene. The translocation has been reported in 20 patients with AML, with eosinophilia present in 3 cases. Here we report a pediatric case of t(16;21)(q24;q22) in de novo AML with eosinophilia and suggest that eosinophilia is a hematologic characteristic of at least a subpopulation of AML with t(16;21)(q24;q22). A 4-year-old Korean girl was admitted with complaints of pale appearance and dizziness, and was diagnosed with acute myelomonocytic leukemia. On admission, laboratory evaluation revealed hemoglobin at 3.3 g/dL, platelets at 9.0 x 10(9)/L, and white blood cells at 9.1 x 10(9)/L with 10% eosinophils and 1% blasts. The bone marrow aspirate contained 31% blasts and 11% eosinophils. Flow cytometric analysis revealed the expression of CD13, CD14, CD19, CD33, CD34, and HLA-DR by the leukemic blasts. The karyotype was 47,XX, + 8,t(16;21)(q24;q22)[18]/46,XX[2]. Interphase fluorescence in situ hybridization analysis with a dual-color, dual-fusion translocation LSI AML1/ETO probe set for RUNX1 and RUNX1T1 produced three signals for each probe in 90% of interphases, but no fusion signals. We confirmed the presence of RUNX1-CBFA2T3 fusion transcripts with reverse transcriptase-polymerase chain reaction, using primers AML1ex5f1 and MTG16r2.
