The radiographs revealed an irregular radiolucent lesion in the anterior part of the mandible. An incisional biopsy was carried out and the microscopy showed features of adenocarcinoma. Suspecting a metastatic lesion, the patient was then sent for whole body examination which showed a mass in the lungs. A whole body scan also showed metastasis to other organs such as kidney, gallbladder and vertebrae. This case is unusual in that the patient complained only of a vague jaw pain with no other systemic symptoms even in the presence of widespread disease.<\/jats:p>","DOI":"10.1136\/bcr-2018-227862","type":"journal-article","created":{"date-parts":[[2018,12,18]],"date-time":"2018-12-18T17:19:47Z","timestamp":1545153587000},"page":"e227862","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":5,"title":["Metastatic
