Figure 2.

BM with large amount of monocytes and myeloid precursor such as promonocytes and cells with immature morphology featuring atypical nuclear anomalies, finely dispersed chromatin, small evident nucleoli and scant cytoplasm. Those cells are CD34 negative but express CD68KP1 and CD68RPGM1 (data not shown). The percentage of immature precursor through the entire BM biopsy has been estimated at about 15 – 20% of all hematopoietic cells. These findings were consistent with the diagnosis of chronic myelomonocytic leukemia- type2 (a). Insert b is a Gomori stain which shows a delicate bone marrow fibrosis, grade-1.
