Auer rods in dysplastic granulocyte

This is a rare and unique case of AML with the characteristic presence of Auer rods in myeloblast and dysplastic granulocyte in association with loss of the Y chromosome. The loss of the Y chromosome is widely reported in myeloid malignancies, whereas presence of Auer rods in mature and dysplastic granulocytes is rare and has been described in AML with maturation. Presence of Auer rods in AML is associated with good prognosis, whereas its significance in dysplastic granulocyte has yet to be determined.
