Introduction. Hepatocellular carcinoma (HCC) is the most frequent primary
malignant tumor of the liver. It is usually seen in the 6th and 7th decades
of life and chronic hepatitis B is the most frequent cause. Extrahepatic
metastasis of HCC is an indicator of a poor prognosis and the most common
sites are lungs, bones, lymph nodes, kidneys and adrenal glands. We reported
a case of isolated metastasis in the right maxilla, which had been found
initially, before the tumor in the liver was diagnosed. Case report. A
70-year-old man underwent dental surgery of the upper right molar. Prolonged
bleeding control was difficult for up to two weeks, so the biopsy was
performed. Histopathological analysis revealed a metastatic hepatocellular
carcinoma. Computerized tomography (CT) of the abdomen revealed a diffusely
heterogeneous liver parenchyma with irregular borders and two foci of mass
lesions. There were metastasis in the spleen and also two pathological
retroperitoneal lymph nodes were detected, but no ascit, liver cirrhosis,
cholestasis or portal vein thrombosis were seen. CT of the orbital and
maxillary regions revealed a tumor mass in the right maxillary sinus,
spreading to the alveolar sinus, nasal cavity and partially infratemporal
space. A tumor mass was in the right orbit as well, infiltrating the
surrounding bones and muscles. Clinically, there was proptosis of the right
eye accompanied by amaurosis. The treatment started with chemotherapy based
on 5-fluorouracil (sorafenib was not available). After three cycles, control
CTs showed a stable disease in the liver, but progression in the right
maxillary sinus and orbit. Enucleation of the right eye was performed and
postoperative radiotherapy was planed. The patient deteriorated rapidly and
died, about 6 months after the disease had been diagnosed. Conclusion.
Extrahepatic metastasis of HCC represents a progressive phase of the disease
with poor prognosis, so the main aim of the treatment should be palliation
and care of symptoms.
