We present a 15-year-old woman with acute myelomonocytic leukemia without marrow eosinophilia, M4 in the FAB classification. She was admitted to our hospital with nausea and headaches. Upon admission, the leukocyte count was 284,000/microliters with 95% leukemic cells. The bone marrow aspirate was hypercellular with 74.8% blasts and 0.2% eosinophils. Leukemic cells were positive for myeloperoxidase and esterase staining. Initially, the karyotype of the bone marrow cells on admission was considered to be normal. However, the PEBP2 beta/MYH11 fusion transcript was detected in the bone marrow mononuclear cells by using the reverse transcriptase-polymerase chain reaction (RT-PCR). Reevaluation of karyotypes showed a t(16;16) (p13;q22) in the bone marrow cells. After achieving complete remission, she was treated with low-dose etoposide. Chromosome analysis showed a normal karyotype and no amplified chimeric transcripts were observed. This case indicates that the molecular analysis of PEBP2 beta and MYH11 genes is a useful tool to detect inv (16) and t(16;16) which were often difficult to find, and that leukemic cells from some cases of M4 without marrow eosinophilia have these chromosome abnormalities.

A 10-year-old boy was admitted to the hospital because of anemia detected after a two week history of fatigue, dizziness, nausea, headaches, and weight loss. A bone marrow investigation confirmed a diagnosis of acute lymphoblastic leukemia of the B-cell precursor phenotype. Chromosome G-banding analysis yielded the karyotype 46,XY,t(17;19)(q22;p13), and fluorescence in situ hybridization (FISH) analysis showed rearrangement of the genes TCF3 (on 19p13; accession number NM_03200 version 3) and HLF (on 17q22; accession number NM_002126 version 4) with the generation of a TCF3-HLF chimera. Polymerase chain reaction and sequencing analyses demonstrated the presence of two in-frame chimeric TCF3-HLF transcripts. In the first one, which corresponds to a type 2 fusion, exon 15 of TCF3 is fused to exon 4 of HLF. In the second, described here for the first time and named type 3, exon 14 of TCF3 is fused to exon 4 of HLF. Whether the type 3 chimeric transcript has the same DNA binding and transcriptional regulatory effect as type 1 and type 2 TCF3-HLF chimeras remains to be seen.
