Figure 1. Electrocardiogram (ECG) showing sinus tachycardia, rate 103 beats per minute, ST segment elevation in leads I, II, aVL and V5 with PR elevation and ST depression in aVR.

Figure 2. Peripheral smear showing increase in myeloid precursors with blasts.
Figure 3.
Figure 3. (a) Low power bone marrow (H&E, × 40) demonstrating a packed marrow. (b) High power bone marrow (H&E, × 200) showing cellular infiltrates with high nuclear/cytoplasmic ratio and prominent nucleoli consistent with myeloblasts. (c) High power bone marrow aspirate with Giemsa-Wright stain (× 600) showing myeloblasts.
Figure 4.
Figure 4. (a) Flow cytometry of the ungated scattergram plot of the marrow aspirate showing a high proportion of events in the dim CD45/low side scatter region (black dots). (b) Blast gate showing expression for CD117 and partial expression for CD34 consistent with blasts.
