Metastases to the mandible are very rare and account for only 1% of all oral tumors. The most common primary in such cases is the breast. Only 20 cases of metastases to the mandible of tumors of the large bowel have been reported. We present the case of a 59-year-old woman with metastatic disease of the mandible in whom the primary tumor was an adenocarcinoma of the sigmoid. Metastases to the oral cavity and mandible should be included in the differential diagnosis of gingival or mandibular lesions in a patient with a previous or current malignancy.
下颌骨转移瘤非常罕见，仅占所有口腔肿瘤的1%。此类病例中最常见的原发肿瘤是乳腺癌。据报道，大肠肿瘤转移至下颌骨的病例仅有20例。我们报告一例59岁女性下颌骨转移瘤病例，其原发肿瘤为乙状结肠腺癌。对于既往或目前患有恶性肿瘤的患者，口腔和下颌骨转移瘤应纳入牙龈或下颌骨病变的鉴别诊断。
