[Translocation t(6;9;8)(p23;q34;q22) in acute myeloid leukemia: Contribution of fluorescence in situ hybridization].

A complex translocation involving chromosome 6, 8 and 9 [t(6;9;8)(p23;q34;q22)] associated with other structural and numerical abnormalities was observed on bone marrow karyotype of a woman suffering with acute myeloblastic leukemia (AML2). Fluorescence in situ hybridization agreed with the conventional cytogenetic interpretation by showing that a part of chromosome 6 short arm was inserted on the rearranged chromosome 9 resulting in the t (6;9) usually encountered in AML.
