We performed cytogenetic studies and breakpoint cluster region (bcr) rearrangement analysis in two cases of juvenile chronic myeloid leukemia (JCML) which is special type of chronic myeloid leukemia (CML). Case 1 (8-month-old male) and case 2 (3-month-old female) showed clinical and hematologic manifestations similar to CML. Each of case 1 and 2 had normal karyotype and no bcr rearrangement. These findings suggest that JCML is a different heterogeneous disorder from that of adult CML.
