A case of mandibular osteomyelitis in a patient with chronic myelomonocytic leukaemia.

We report a case of chronic myelomonocytic leukaemia (CMMoL) in a 68-year-old man who developed osteomyelitis of the mandible. At the initial visit, he reported uncontrolled gingival bleeding, despite self-administered haemostasis. He complained of severe pain in the socket, despite potent opioid analgesia. After consultation with the internal medicine specialists, we undertook a surgical anti-inflammatory approach that included sequestrectomy with massive blood transfusion. His physical condition was ameliorated after the surgical procedure, and he was discharged from the hospital. However, 3 months later, he died because of cardiac arrest after haemorrhagic shock and cardiovascular failure because his CMMoL had developed to an acute blastic crisis. This experience demonstrates that the most important goal in such cases is to alleviate a patient's discomfort by applying minimally invasive actions to eliminate infection and improve the quality of life without causing deterioration in the CMMoL status.
