case_images: (A) Flow cytometry analysis of the patient. It shows approximately 22% infiltration of immature T-lineage lymphoblastic cells. Immunophenotype presented CD7, CD34, cCD3, CD5 are positive. (B) The immunophenotype of the flow cytometry showed CD79a, MPO are negative.

case_images: CD34, cCD3, CD5), which was similar to that of the lymph node tissue (Figure 1). TCR beta (TRB), TRD, TCR gamma (TRG), immunoglobulin heavy (IgH), light chains kappa (IgK), and lambda (IgL) rearrangement were negative. Cytogenetic analysis was implemented with R-banding showed a noncomplex karyotype: 46XY, (9:22) (q34;q11) [1]/46, XY, [19] (Figure 2), and fluorescence in situ hybridization (FISH) confirmed the presence of a translocation of 9q34 (ABL1) to 22q11 (BCR) in 18% of the nuclei (300 nuclei were analyzed) (Figure 3).

case_images: Fluorescence in-situ hybridization(FISH) showed location of the probes. One green BCR signal, one red ABL signal and two yellow fusion signals: BCR-ABL and ABL-BCR indicating the presence of BCR-ABL translocation in the lymphoblasts.
