KIT D816V Positive Acute Mast Cell Leukemia Associated with Normal Karyotype Acute Myeloid Leukemia

Figure 4

Peripheral blood dot plots obtained by flow cytometry showing 3% of CD117+ CD34+ myeloid precursor cells (black dots) and 49% of CD117+ CD34-mast cells precursors (orange dots). Please note that circulating myeloid precursor cells (black dots) and mast cells precursor (orange dots) had an immunophenotype like that observed in bone marrow (BM) myeloid precursor cells and BM mast cell precursors, respectively (please cf. Figure 3, same color code). Please also note that the relatively mature mast cells observed in BM (red dots, Figure 3) were not present in the peripheral blood.
