78歳の女性が65歳で乳癌のために左乳房全摘術を受けた。病理所見では乳癌の肝転移が認められたが，胆管細胞癌との鑑別が困難な乳癌の単発肝転移症例では肝切除術が有用である．

A 78-year-old woman underwent left total mastectomy for breast cancer at 65 years of age.Thirteen years after the primary surgery, CT showed a single 46mm tumor located in liver segment 4.The tumor was difficult to distinguish between cholangiocellular carcinoma and liver metastasis of the breast cancer.We did not perform biopsy, considering dissemination, and performed left hemihepatectomy and left caudate lobectomy.Pathological findings revealed liver metastasis of breast cancer.Hepatic resection is a useful option in cases of single liver metastasis from breast cancer that are difficult to distinguish from cholangiocellular carcinoma.
