title: [Lung cancer reveal by mandibular metastasis: a case at the Centre of Consultation and Dental Treatment Dental of Casablanca (CCDTC)].
abstract: Metastatic tumors result from hematogenous spread through a tumor located at a distance. All these tumors represent about 1% of malignant tumors of the oral cavity (1). The most common location is the mandible (70%), more rarely maxillary (2). The most frequently encountered tumors are carcinomas or adenocarcinomas of mammary origin, brocho-lung, prostate, kidney or another. This study reports the case of a 46 year-old man, who presented for consultation with a low left laterofacial swelling, paresthesia lip and chin straight associated with pain at the lower edge of the mandible evolving for 2 months. The patient is known to take alcohol and tobacco for 20 years. The panoramic radiograph showed radiolucent image with blurred boundaries at the lower right premolar region. Dentascan revealed an irregular osteolytic lesion with rupture of the table lingual. After surgical exploration, the pathological examination is for a well-differentiated and invasive adenocarcinoma of the mandible. Extension work-up shows the presence of a tumor right lung, a lytic lesion at the 8th costal arch, the fourth dorsal vertebra and another location in fibula. The surgical exploration of pulmonary was performed and confirmed the pulmonary primitive localization of adenocarcinoma.
