Abstract

Hepatocellular carcinoma is a fatal disease with median survival less than 6 months. About 50% of hepatocellular carcinoma patients showed distant metastasis at earlier stage. Common metastatic sites are lung, intraabdominal lymph nodes, adrenal gland or bone, in order of frequency. Renal metastasis from hepatocellular carcinoma is rare with the incidence of 1.2-4.3% at autopsy. Lack of clinical symptoms and signs make it difficult to diagnose metastatic renal cancer before dying of. Common primary sites of metastatic renal cancer are malignant lymphoma, lung, stomach or breast. We report a case of hepatocellular carcinoma with renal metastasis. A 54 female patient was found to have coincidental right hepatic and right renal tumors on abdominal ultrasonographic and computed tomographic examinations. After the percutaneous needle biopsy on the right hepatic tumor and right renal tumor, histopathologic and immunohistochemical studies ultimately confirmed the diagnosis of hepatocellular cracinoma with renal metastasis. Intraarterial chemotherapy with cisplatin for primary hepatocellular carcinoma and intraarterial embolization for renal metastatic lesion were performed.
