Auer rods in mature granulocytes in peripheral blood

Published in:

Excerpt

A 55-year-old man with agranulocytosis was diagnosed with acute myeloid leukemia (AML). Atypical eosinophil granulocytes with large basophil but also small pale, structureless granules were observed, and cells with Auer rods in maturing granulopoiesis were noticed in the bone marrow. Panel A shows a mature granulocyte in peripheral blood with many Auer rods in cytoplasm (Pappenheim stained peripheral blood smear, 1000x; Supplementary Material). Auer rods were visible in the peripheral blood in 8% (4/50) of the mature granulocytes. Panel B shows fluorescence-in-situ-hybridization with inversion 16 [inv(16)(p13q22)] in a bone marrow blast due to rearrangement (split; red and green) of a CBFB copy (1000x) (Fig. 1).
