Hepatocellular carcinoma metastatic to the mandible.

A case of hepatocellular carcinoma metastatic to the mandible is described. The patient reported swelling, pain, and trismus after a pathologic fracture. After a systematic examination with the use of 99mTc-methylene diphosphonate, 67Ga-citrate, and 99mTc-pyridoxyl-5-methyl triptophan scintigraphy the primary focus was discovered in the right lobe of the liver. The focus was confirmed by computed tomography and magnetic resonance imaging. The histopathologic diagnosis of hepatocellular carcinoma was made from a biopsy specimen of the mandibular lesion.
