The diagnosis of myelogenous leukaemia in a patient presenting with acute gingival hypertrophy and a high white blood cell count is supported by the association between blood disorders and oral manifestations. Myelogenous leukaemia, particularly acute myeloid leukaemia (AML), can lead to the infiltration of leukemic cells in the gingival tissues, resulting in hypertrophy or swelling of the gums.

In this clinical scenario, the significant elevation in white blood cell count indicates a hematological issue, which aligns with the pathophysiology of leukaemia, where abnormal cell proliferation occurs. This can manifest in the oral cavity, including symptoms such as gingival hyperplasia, which is often noticeable.

Other conditions listed, such as infectious mononucleosis, can cause systemic symptoms and possibly gingival changes, but they are less characterized by the level of gingival hypertrophy seen in leukaemia. Thrombocytopenic purpura primarily leads to bleeding tendencies rather than pronounced gingival enlargement. Gingivitis of local aetiological origin usually does not present with such a high white blood cell count and is more related to local factors such as plaque accumulation.

Thus, the combination of acute gingival hypertrophy and a markedly
