Abstract

Oral metastases from hepatocellular carcinoma are very rare. We encountered a case of hepatocellular carcinoma with a solitary metastasis to the mandible as an initial manifestation. The patient was a 76-year-old man who was admitted for left mandibular swelling. A biopsy specimen of mandible was suspected to be a metastatic tumor. The histological findings, abdominal computed tomography, bone scintigraphy, and F-18 fluorodeoxyglucose-positron emission tomography (FDG-PET) revealed it to be a solitary metastasis from hepatocellular carcinoma. As a result, he was diagnosed to have liver cirrhosis due to a hepatitis C virus infection and hepatocellular carcinoma with a solitary metastasis to the mandible. The primary lesion was treated with transcatheter arterial embolization (TAE), and the metastasis to the mandible was surgically resected. The patient survived for 9 months after treatment without recurrence.
