We report a case of primary leiomyosarcoma of the liver in a 76-year-old, woman. Ultrasonography showed hypoechoic tumor growth over time in hepatic segment VIII. Computed tomoraphy and angiography did not detect the tumor. We conducted percutaneous liver biopsy. In histological study, including immnohistological study, the lesion was found to be leiomyosarcoma. After embolization of the right hepatic artery and right portal vein, we conducted extended right hepatectomy. The tumor consisted of malignant spindle cells in necrotic tissue. Tumor cells were positive for vimentin and alpha-smooth muscle actin in immunohistochemical staining.
