Background: Hepatocellular carcinoma (HCC) is the most common primary hepatic tumor and one of the most common cancers worldwide. HCC is a primary malignancy of hepatocellular origin. Objectives:The aim of study is to combinate therapy of transarterial chemoembolization and percutaneousethanol injection afterward emerging metatasis caused by fine needle aspiration cytology. Subjects and method: A 50 years old male patient with hepatocellular carcinoma having a diameter of tumor more than 5 cm was treated by combination of transarterial chemoembolization and percutaneous ethanol injection from December 2000. Results & Conclusion: Results of study showed that: Transarterial chemoembolization and percutaneous ethanol injection are the two of non-surgical methods for treatment of hepatocellular carcinoma which are most commonly available in applied clinical activities at present. Up to now, the patient's life expectancy after therapy is more than 6 years that means the result of treatment is very good. However, the emerging metatasis into the anterior-right-Iower chest wall that was caused by fine needle aspiration cytology should be reviewed for further evaluating clinical experience, especially in cases with quite clear imaging features of untrasonography and significantly elevated AFP level higher than 200 ng/rnl.

Hepatocellular carcinoma (HCC) with sarcomatous features is a rare neoplasm which has been found in only 1.8% of surgically resected HCC and has a higher incidence of metastasis than usual HCC. We recently experienced a case of sarcomatoid HCC removed from a 49-year-old man. A surgically resected liver revealed a well-defined grayish-white solid firm mass showing extensive central necrosis and infiltrative growth margin. Microscopically, the entire tumor was composed of pleomorphic spindle cells with prominent nucleoli and frequent mitosis. It showed a sinusoidal infiltrative growth pattern at the tumor-nontumor boundary. The tumor cells reacted positively with AE3 (high molecular cytokeratin) and Vimentin and reacted negatively with AE1 (low molecular cytokeratin), cytokeratin19, carcinoembryonic antigen, alpha-fetoprotein, Factor VIII, CD31 and CD68. The spindle-shaped tumor cells were considered to originate from hepatocyte rather than from bile duct epithelium or mesenchymal elements.
