[Mandibular metastases from colonic adenocarcinoma].

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.
