Lung cancer is the most frequent cause of cancer-related death worldwide. While metastases of lung malignancies to the oral cavity are rare, it is the most common neoplasm to metastasize to this region. Diagnosis of a metastatic lesion in the oral cavity is challenging for clinicians and pathologists, but is critical in improving patient outcomes. This report presents a case of a 75-year-old female with lung adenocarcinoma metastatic to posterior left mandible. A literature review of cases of lung cancer metastasis to the oral and maxillofacial region between 2015 and 2022 was conducted and compared with prior research.
