J Stomatol Oral Maxillofac Surg. 2018 Jun;119(3):229-231. doi: 10.1016/j.jormas.2018.02.003. Epub 2018 Feb 21.

Abstract

Introduction: Metastatic carcinoma of the colon is frequently encountered. In the literature, metastasis of malignant tumors in the buccal cavity are rare. They represent less than 1% of oral malignant lesions.

Observation: We present a case of oral metastasis of colon adenocarcinoma in the mandible of a 62-year-old patient. The physical examination revealed a swelling in the mandibular symphysis associated with dental displacement. The panoramic X-ray showed significant bone lysis of the symphysis. The neoplastic tissue showed marked positivity for Cytokeratin 20 and CDX2, confirming the diagnosis of metastasis of the oral cavity from colorectal adenocarcinoma.

Discussion: Metastatic adenocarcinoma from the colon to the oral cavity are rare but should be included in the differential diagnosis of tumors in the oral cavity.

Keywords: Colonic neoplasms; Neoplasm metastasis; Oral.
