ABSTRACT
<p><b>OBJECTIVE</b>To report five cases of acute myeloid leukemia (AML) with t(16;21)(p11;q22) translocation and the result of chromosome painting analysis on one of them.</p><p><b>METHODS</b>Chromosome specimens were prepared by short-term culture of bone marrow cells. Karyotype analysis was made by R-banding technique. Chromosome painting was performed using whole chromosome probes 16 and 21 in 1 case.</p><p><b>RESULTS</b>Karyotype analysis showed identical translocation t(16;21)(p11;q22) in all five cases, accounting for 0.3% of 1448 cases of acute myeoid leukemia examined in the past fifteen years. Moreover, chromosome painting distinctly demonstrated t(16;21) in one of them. Leukemia blasts did not show hemophagocytosis in all of them.</p><p><b>CONCLUSION</b>t(16;21) translocation is a rare and recurring chromosome rearrangement. It represents a specific type of AML. Chromosome painting technique is a more reliable means for detecting it, compared with the conventional karyotype analysis.</p>
