RESUMO
OBJECTIVE: In this retrospective study, we assessed the efficacy of hepatic arterial infusion chemotherapy (HAIC) using high-dose 5-fluorouracil (5-FU) and cisplatin with or without interferon (IFN)-alpha for the treatment of advanced hepatocellular carcinoma (HCC) with portal vein tumor thrombosis. MATERIAL AND METHODS: Fifty-two patients were included in the analysis. The patients were treated with 5-FU (750 mg/m(2)) and cisplatin (25 mg/m(2)) from Days 1 to 4. IFN-alpha was administered subcutaneously at a dose of 3 million units from Days 1 to 4, and then every other day for 24 days. Chemotherapy was repeated every 4 weeks. Thirty-one patients were treated with 5-FU, cisplatin and IFN-alpha (FPI group) and 21 were treated with 5-FU and cisplatin (FP group). RESULTS: An objective tumor response was achieved in six patients (19.4%) in the FPI group. In the FP group, 12 patients (57.1%) achieved an objective tumor response (p = 0.015). The cumulative survival rate was higher in the FP group than the FPI group, but this difference was not statistically significant (p = 0.353). The median survival time for the 18 responders was 14 months (range 4-25 months), and their 6, 12, and 24-month cumulative survival rates were 89%, 83%, and 25%, respectively. CONCLUSIONS: HAIC using high-dose 5-FU plus cisplatin achieved a good tumor response. Adding IFN-alpha did not show any additional beneficial effects in terms of tumor response rate or survival.

Undifferentiated carcinoma with osteoclast-like giant cells is a rare neoplasm of exocrine pancreas. Till recently, some cases have been reported, however histogenesis of the tumors are controversial and their characteristic findings have not been described yet. Thirty five-year-old men and 75-year-old men were presented with upper abdominal pain and a palpable mass. On computed tomography, one case showed a well enhancing solid tumor with low density and the other was showed a mainly cystic tumor with peripheral enhancement in the body and tail of the pancreas. One case accompanied multiple metastatic liver masses with subhepatic lymph node enlargement. Tumor staining was seen on angiography. Biopsy and pancreatectomy were performed. Pathological findings revealed tumors composed of neoplastic spindle shaped or pleomorphic large cells with scattered non-neoplastic osteoclast-like giant cells. In one case, there were small foci of adenocarcinoma components in the periphery of the tumor. On immunohistochemical stain, neoplastic cells showed focal positivity for epithelial membrane antigen and vimentin. Tumors were diagnosed as undifferentiated carcinoma with osteoclast-like giant cells. We report these rare cases with a review of literature.

Primary adenosquamous cell carcinoma of the liver, a variant of cholangiocarcinoma is very rare disease and its prognosis is known to be very poor. We describe here a case of primary adenosquamous carcinoma of the liver. The patient was a 60-year-old woman who complained of an eight-month history of intermittent upper abdominal pain. Abdominal computed tomography scan revealed a low density mass and intrahepatic duct stones within the dilated left intrahepatic duct in the left lateral segment. Needle biopsy of the mass was done and the histologic diagnosis was cholangiocarcinoma. Left lobectomy was then performed. Upon gross examination, there was a well defined solid mass and intrahepatic duct stone in the dilated bile duct. Microscopically, the tumor was composed of both adenocarcinoma and squamous cell carcinoma.

Cures for advanced hepatocellular carcinoma (HCC) with portal vein tumor thrombosis (PVTT) are rare and difficult. We report a case of pathologically confirmed complete remission of HCC induced by hepatic arterial infusion chemotherapy (HAIC). A 45-year-old male patient had a massive HCC in the right lobe of the liver and tumor thrombus in the right and main portal veins. He achieved a partial response after two cycles of HAIC with 5-fluorouracil (750 mg/m(2)) and cisplatin (25 mg/m(2)). After the completion of six cycles he received a curative partial hepatectomy, and histopathology revealed complete necrosis without any viable tumor cell. He was in good health at a 4-month follow-up. These results suggest that this regimen is a promising therapeutic modality for the treatment of advanced HCC with PVTT.
RESUMO
Intrahepatic biloma is one of the rare complications occurring after transcatheter arterial chemoembolization (TACE). Biloma after TACE may result from the development of peripheral bile duct necrosis caused by microvascular damage of the peribiliary capillary plexus, and intrahepatic ductal stenosis. We report a case of resection of intrahepatic biloma with hepatocellular carcinoma after TACE.

OBJECTIVE: The purpose of this study is to analyze the sonographic and MR imaging findings of testicular epidermoid cysts. CONCLUSION: Sonographic findings of a markedly heterogeneous intratesticular mass with or without alternating hypo- and hyperechoic layers surrounded by a hypoechoic or echogenic rim and the absence of flow on color Doppler sonography suggest the preoperative diagnosis of testicular epidermoid cysts. T2-weighted MR imaging findings of a high-signal-intensity mass with or without low-signal-intensity foci surrounded by a low-signal-intensity rim and the absence of enhancement on contrast-enhanced T1-weighted MR images can strengthen the preoperative diagnosis. These imaging findings can offer a basis for surgeons to attempt testis-sparing surgery instead of orchiectomy.
