Two new chromosomal abnormalities in chronic myelogenous leukemia 46,XY,t(9;15;22)(q34;q22;q11) and 46,XY,t(6;9;12;22)(p21;q34;q24;q11).
Two new variant cases of chronic myelogenous leukemia (CML) are presented. The first case is a 19-year-old male with a 46,XY,t(9;15;22)(q34;q22;q11) karyotype. The second case is a 75-year-old man with a 46,XY,t(6;9;12;22)(p21;q34;q24;q11) karyotype. In both cases, the prognosis was no different from those cases of CML with the standard t(9;22) as the only abnormality. We recommend that all unusual translocations be reported.
