Dear Juan, After I've seen your attached file my first idea was that your case may be an acut myeloid leukemia. In my opinion the population what you reported as monocytes are myeloid blasts wich is supported by the findings of the CD45/SSC pattern , the CD34 and myeloid marker (13, 33, MPO) positivity. The CD19 may be an aberrant expression of this B-lineage marker. Best regards, Pal Jakso University of Pecs Faculty of Medicine Dept. of Pathology 7643, Hungary 12. Szigeti str.
