- Hepatocellular carcinoma (HCC) is the fifth most common cancer worldwide in terms of incidence. The majority of tumors
are diagnosed when advanced. The long-term prognosis of HCC remains poor, with a 5-year survival rate of <5%. However,
recent progress in the treatment of HCC has made it possible for the patient to survive longer, and as a result, distant
metastasis from HCC, including bone metastasis has increased and attracted more attention than before. Of the various
metastatic sites, the most common site is the lungs, followed by the lymph nodes and bone. The most frequent sites of bone
metastasis are the spine, pelvis and rib in that order. Single bone lesion was associated with a favorable outcome, while
multiple bone lesions may be associated with severe pain and increasing rate of leucopenia, anemia, and thrombocytopenia,
sometimes making radiotherapy administration difficult. The incidence of bone metastasis in HCC is low. Moreover HCC
diagnosed with bone metastasis is very rare. We report a patient who present with bone metastasis before the diagnosis of
a primary cancer.
