KIT and mixed phenotype acute leukemia: On flow cytometry, blasts comprise 19% of total nucleated cells, expressing CD45 weak+, CD117+, C34−, CD33−, CD38+, interestingly also CD7+, and cytoplasmic CD3 weak+.  The blasts therefore demonstrated features of both myeloid (CD117, MPO) and T‐lymphoid (cytoplasmic CD3) lineages, consistent with mixed phenotype acute leukaemia (MPAL), which had most likely transformed from MDS‐EB2.
