Hepatocellular carcinoma (HCC) is one of the most common malignancies in Korea. Extrahepatic metastases
from hepatocellular carcinoma are not rare and now diagnosed more frequently due to improved diagnostic
methods
and prolonged survival. HCC commonly metastasizes to lung, lymph node, bone and adrenal gland, but
rarely to central nervous system, gastrointestinal tract, oral cavity, and so on. Diagnosis of extrahepatic
metastases is difficult because of atypical presentation. We report two cases of hepatocellular carcinoma, which
metastasized to mandible and mesentery, respectively.
