Metastatic tumours of the jaw are overlooked due to their relatively rare incidence. However, they are often the first indicators of an unknown primary malignant lesion. In this case report, we present a 68-year-old male patient with a suspected intraosseous malignancy of the mandible who was treated by a right segmental mandibulectomy. The final histopathology report was indicative of a secondary metastatic tumour. Positron emission tomography scan revealed a suspicious lesion in the right lung, which was identified as the primary tumour by biopsy using the Tru-Cut® biopsy device (MeritMedical, Jordan UT). The metastatic lesion to the oral soft tissues was easily recognized, in contrast to the jawbone metastasis. Differentiating between primary intraosseous and metastatic mandibular tumours relies on the histopathologist and the surgeon working in tandem to arrive at an early conclusive diagnosis. Knowledge of metastatic tumours to the facial bones is indispensable to a surgeon as it can often be the first indication of an unknown primary malignancy. Identification of early signs, appropriate and timely investigative procedures, coordination between pathologist and surgeon, and choosing the correct treatment modality can help prolong and improve the quality of life of the patient.
