Figure 2 A chromosome study and fluorescence in situ hybridization study. A: Giemsa-banding karyogram at initial diagnosis: 46, XX, t(11;19)(q23;p13.1). The arrows indicate the involved chromosomes; B: Metaphase fluorescence in situ hybridization with the KMT2A probe revealed a red signal on the derivative chromosome 19, a green signal on the derivative chromosome 11, and a fusion signal on the normal chromosome 11.
