Acute myeloid leukaemia (AML) is a highly heterogeneous disorder and is characterised by the proliferation of poorly differentiated myeloid cells due to underlying mutation, eventually causing bone marrow failure. Accounting for approximately 25% of cases, AML is the most frequent form of leukaemia in the world yet has the lowest survival rate among all leukaemias. Patients with haematological malignancy are more susceptible to severe acute respiratory syndrome coronavirus-2 infection and further development of severe infection, including pneumonia with poor blood oxygenation. The management of such patients is more challenging than expected. Successful management of one such case is discussed in this report. COVID-19 infection can cause great harm to a patient with underlying leukaemia and increase the mortality risk. It has a major impact on the physical and psychological health of the patient. Therefore, these patients need special care and attention. The authors emphasise the importance of supportive management (oxygen with bilevel positive airway pressure, prone positioning, and physiotherapy) to prevent complications.
