Slide 5: PB of AML

	PB of AML: presence of at least 30 percent myeloblasts in blood and/or bone marrow. (figure 1)
	Myeloblasts: nuclear chromatin that is uniformly fine or lacelike in appearance and large nucleoli (two to five per cell). (figure 2) If specific cytoplasmic granules, Auer rods, or the nuclear folding and clefting characteristic of monocytoid cells are not present, the morphologic features observed under light microscopy may not be sufficient to clarify the diagnosis. (figure 3)
