On a cytological preparation from a patient with acute myeloid leukemia, a large number of Auer rods were observed in blast cells. In one of the blasts, the stage of Auer rod formation was captured.
Auer rods are formed as a result of the fusion and aggregation of abnormal primary granules (lysosomes) containing myeloperoxidase and other lysosomal enzymes.
