Metastatic lesions to the mandible are rare, comprising less than 1% of all malignancies. A 75-year-old gentleman presented to ENT outpatient with a 3-week history of numbness over his lower lip on the right side followed by a rapidly growing swelling in his right mandibular region. The patient was diagnosed with an obstructing sigmoid tumour with metastasis to the liver and retroperitoneal adenopathy, 5 months ago. A colonic stent was inserted for the sigmoid tumour and patient was undergoing palliative chemotherapy. CT scan of the mandibular region showed mass lesion invading the ascending ramus of mandible and involving the right inferior alveolar nerve. Trucut biopsy confirmed metastatic adenocarcinoma.
下颌骨转移瘤罕见，占所有恶性肿瘤的比例不到1%。一名75岁男性因右侧下唇麻木3周，随后右侧下颌区域迅速肿胀，前来耳鼻喉科门诊就诊。该患者5个月前被诊断为乙状结肠肿瘤伴肝转移及腹膜后淋巴结肿大。已为乙状结肠肿瘤置入结肠支架，患者正在接受姑息化疗。下颌区域的CT扫描显示肿块侵犯下颌骨升支并累及右下牙槽神经。粗针活检证实为转移性腺癌。
