Abstract
- The ider(22)(q10)t(9;22)(q34;q11.2) is a rare secondary karyotypic aberration of Philadelphia chromosome positive chronic myelogenous leukemia (Ph+ CML) and was associated with disease progression and poor clinical outcomes in most of the previously reported cases. We experienced a case of Ph+ CML with the occurrence of ider(22)(q10)t(9;22)(q34;q11.2) as clonal evolution preceding an hematologic feature of accelerated phase for 3 years. So this chromosomal abnormality was not always correlated with poor prognosis. Relevant literature was reviewed.
