Breast metastasis from a hepatocellular carcinoma / 대한내과학회지

Hepatocellular carcinoma is so highly invasive that distant metastases are commonly observed at the time of diagnosis. The common sites of extrahepatic metastasis are lung, local lymph node, adrenal gland and bones. A breast metastasis from a non-mammary malignancy is rare, accounting for approximately 2% of breast tumors. We experienced a patient with hepatocellular carcinoma who had suffered from a huge breast mass, which was diagnosed as a metastasis of hepatocellular carcinoma. To our knowledge, this is the first report of a metastatic hepatocellular carcinoma of the breast in Korea.
