Unusual Presentation of an Adenocarcinoma of the Lung Metastasizing to the Mandible, Including Molecular Analysis and a Review of the Literature.

Lung cancer is the most frequent cause of cancer-related death worldwide. Metastases of non-small cell lung carcinoma to the oral and maxillofacial region are rare. Thus, the diagnosis of a metastatic lesion in the oral cavity is challenging to the clinician and to the pathologist. This report presents a case of a 72-year-old man with metastatic lung adenocarcinoma located in the posterior mandibular region. Next-generation sequencing analysis showed no important mutations in the relevant genes except in the TP53 tumor suppressor gene.
