Metastasis of a gastric adenocarcinoma to the mandible

AbstractMetastatic tumors of the oral cavity are rare, representing about 1% of oral tumors. Here we report the case of a 51-year old woman presenting with a swelling in the oral cavity and had a history of a surgically treated gastric adenocarcinoma. In oral examination, a non-tender bulging mass was detected in the left side of the body of the mandible. The OPG film revealed a radiolucent lytic lesion in the posterior area of the mandible. The tumor showed irregularly shaped small and large cystically dilated glands underneath the overlying oral epithelium. The mandibular lesion was diagnosed as metastatic gastric adenocarcinoma
