title: Hepatocellular carcinoma metastatic to the oral cavity including the maxilla and the mandible: report of two cases and review of the literature.
abstract: Two cases of hepatocellular carcinoma metastatic to the oral cavity are presented. One patient had metastases to the maxilla and finally, to the mandible, and the other patient, to the mandible. Both cases histologically showed highly-differentiated trabecular hepatocellular carcinoma which had vascularized stroma, explaining the frequently observed oral hemorrhage. The clinical signs and symptoms described here suggested the existence of a tumor metastatic to the oral cavity, and might indicate an unusual manifestation of hepatocellular carcinoma. Reports of metastatic lesions of hepatocellular carcinoma to the oral cavity, including the mandible, maxilla and gingiva proper, are reviewed.
