All cancer patients, particularly those treated for colorectal cancer, should be monitored for the presence of liver metastases, but liver metastases from ovarian clear cell carcinoma are quite rare. We report a patient subjected to extended left hepatectomy due to a giant metastasis 5 years after surgical treatment for an ovarian neoplasm that was histopathologically diagnosed as clear cell carcinoma. A 58-year-old woman had undergone hysterectomy and bilateral salpingo-oophorectomy due to ovarian cancer (stage Ic). Four years and 8 months after the operation, a computed tomography (CT) scan demonstrated a giant tumor in the left lobe of the liver. The tumor compressed the inferior vena cava (IVC), but it was not clear whether it invaded the vessel. She received chemotherapy for 4 months; however, the tumor did not decrease in size. She was subsequently referred to our institution and was submitted to operation after it was confirmed that there were no distant metastases. After being subjected to an extended left hepatectomy and cholecystectomy, the patient recovered from the surgery without any complications. She has been carefully followed for 17 months and has presented no evidence of recurrence.
