Discovery of a Poly-metastatic Pulmonary Adenocarcinoma Following the Diagnosis of a Bone Lesion in the Mandible: A Case Report

Introduction: Metastases of the oral cavity are rare and concern only a tiny part of the neoplasias of the oral cavity. The detection of an atypical lesion should always alert the clinician to the possibility of primary or secondary cancerous involvement. Observation: The case presented here describes a patient presenting to the consultation for pain in the temporomandibular joint. A panoramic X-ray revealed an atypical osteolytic lesion located at the level of the left articular condyle. Additional investigations confirmed the existence of a lytic lesion indicating a metastasis or a primary sarcomatosis type. Complementary examinations made it possible to establish the diagnosis of a poly-metastatic pulmonary adenocarcinoma and to begin the management of the patient who was unaware of her condition. Conclusion: The discovery of an atypical bone lesion should alert the clinician and requires the performance of additional examinations to establish a diagnosis that can condition the survival of a patient.
