Prominent megakaryocytic dysplasia is frequently observed in such cases. Note the multi-nucleated and non-lobated megakaryocytes with widely separated round nuclei (black arrow). One of the most reliable features of megakaryocytic dysplasia is the presence of a micromegakaryocyte (red arrow), which is approximately the size of a promyelocyte. Aberrant CD34 expression is often noted in dysplastic megakaryocytes and should be differentiated from blasts.

Scattered dysplastic neutrophils in the smears are notable for cytoplasmic hypo-granularity, abnormal nuclear segmentation and increased chromatin clumping (purple arrow) when compared to normal neutrophils (green arrow).
