AML with multilineage dysplasia - BM
Description: There are three myeloblasts in the picture, one of them underneath the centre with cleft nucleus. Three immature cells of erythroid lineage (proerythroblast and two more or less mature early normoblasts) belong to cells localized around the picture's centre. At 5 o'clock lays one dysplastic cell of perhaps granulocytic or may be monocytic lineage; it has band-like but really immature nucleus with fine chromatin and clear nucleoli and immature cytoplasm without granulation. Another almost bizarre cell is in the centre, it the most probably belongs in granulocytic series, it has moderately mature nucleus, basophilic cytoplasm almost without granulation but with one digested late normoblast.

AML with multilineage dysplasia - BM
Description: There are seven myeloblasts underneath the centre of the picture and three proerythroblasts at the upper left. Between these two groups of the cells lies one agranular band and one red mitosis. Two early polychromatophil red cells precursors (upper left) have megaloblastoid nuclear pattern and they are bilobated. Three late polychromatophil normoblasts (to the left and down from the centre) have pycnotic nuclei.
