AUER rods are seen in
Acute myelogenous leukaemia (AML)
AML is a cancer of myeloid line of WBCs, characterized by the rapid proliferation of abnormal cells which accumulate in the bone marrow and interfere with the production of normal blood cells,
AML is the most common acute leukaemia affecting adults.
The diagnosis of AML is based on finding that myeloid blasts make up more than 20% of the cells in the marrow,
Myeloblasts are myeloperoxidase (peroxidase positive)
Auer rods (represent abnormal azurophilic granule) are also present in myeloblasts and their presence is taken to be definitive evidence of myeloid different.
In some AMLs, blast cells exhibit different of other myeloid stem cell line (other than myeloblast),
e.g., Monoblast → Lack Auer rods, peroxidase negative, but nonspecific esterase positive. Megakaryocyte different Erythroblast
