Abstract: Primary liver cancer is one of the most common cancers which endanger human health.
Hematogenous metastasis and lymphatic metastasis are two major ways of extrahepatic metastasis for primary
liver cancer. The most common sites of extrahepatic metastasis are lung, followed by lymph nodes, bone and
adrenal glands. Direct invasion and metastasis of the thoracic wall is rare. In this paper, a case of primary liver
cancer with direct invasion of thoracic wall was reported.
