Auer stick
Auer rods are small, rod-shaped, azurophilic granules that are found in the cytoplasm of myeloblasts and promyelocytes in the course of leukemia .
Auer rods are found in about 30% of cases in acute myeloid leukemia (AML) and in myelodysplastic syndromes. These are irregular cell organelles that contain lysosomal enzymes and are signs of a malfunction of the cell.
Cells that have multiple Auer rods in bundles are called Fagot cells . They can occur in promyelocytic leukemia (AML-M3).
