Chronic myeloid leukemia with a rare variant Philadelphia translocation: t(9;10;22)(q34;q22;q11).

ABSTRACT

We report a 59-year-old, male, chronic myeloid leukemia patient with a rare variant Philadelphia (Ph) translocation t(9;10;22)(q34;q22;q11). Fluorescence in situ hybridization with whole chromosome paints was used to confirm the cytogenetic findings. With a BCR/ABL-specific probe, the known rearrangement on the derivative chromosome 22 was found. The prognostic implications as well as the relevance of the additional breakpoint region 10q22 are discussed.
