Abstract：
:Auer rods are cytoplasmic inclusions found only in the leukaemic cells of some cases of acute myeloid leukaemia (AML). The ultrastructure of Auer rods is different in different sub-types of the disease and it is suggested here that this may be a consequence of the Auer rods consisting of different crystalline forms of the enzyme myeloperoxidase. There is statistical evidence to indicate that patients with Auer rods have a more favourable prognosis than those without. It is proposed that an investigation of the factors that determine the form, if any, of the crystallisation of myeloperoxidase will lead to a better understanding of the molecular events underlying the different types of AML. In the long term this may in turn lead to a therapeutic advance.
