Peripheral blood smears and bone marrow (BM) biopsies. (A) PB smear on 5 March 2013 shows leukocytosis and monocytosis with mature monocytes. B and C BM aspirate (B) and biopsy (C) on 5 March 2013 shows hypercellular marrow with granulocytic and monocytic hyperplasia with no increase in blasts. (D) PB smear on 20 May 2013 shows marked leukocytosis with dysplastic granulocytes, monocytes and myelocytes. E and F. BM aspirate (E) and biopsy (F) on 20 May 2013 shows 100% cellularity with groups of blasts and multiple mitotic figures (arrow head).
