PG - 9-11 AB - A patient with acute myeloblastic leukemia (AML) and karyotypic abnormality mimicking t(8;21) is reported. Because of the uncommon morphology of blasts for AML with t(8;21), and absence of AML1-ETO fusion in the RT-PCR analysis, fluorescence in situ hybridization (FISH) was applied to precise the abnormality. FISH revealed a complex rearrangement involving chromosomes 7, 21 and 8, and involvement of the AML1 gene without evidence of AML1-ETO fusion. This case of unusual AML illustrates the necessity of collecting all hematologic, cytogenetic, and eventual FISH and RT-PCR data to analyse genetic rearrangements in leukemic patients.
