The blasts appear undifferentiated. One of the four shows some granules.	The cells are positive for CD33 CD13 as well as for cytoplasmic CD3 and other T cell markers (W.-D. Ludwig)	Again a blast with some granules.
Some of the larger blasts are positive for peroxidase.	Even the small blast in the middle shows positivity for peroxidase	Sometimes peroxidase positivity is as faint as in the cells near the top.
CD13: 95%, CD33 73%, 3cyto 88%, CD5 94%, CD2 92%, CD7 92% TdT 90% (W.-D. Ludwig)	Even some Auer rods could be found.
