Cholangiocarcinoma is a malignant disease of the epithelial cells in the intra- and extrahepatic bile ducts. It is the most frequent biliary malignancy. The lack of effective medical treatment makes a radical surgical resection the only therapeutic option. However, frequently Intrahepatic cholangiocarcinoma metastasize in lymphatic chains, including the hepatoduodenal ligament, and it often inv...
Cutaneous metastasis of cholangiocarcinoma is extremely rare. It can be seen at distant locations or at the site of biliary drainage. To the best of our knowledge less than 30 cases have so far been reported in the English literature. This event should be considered in every skin lesion in a patient with cholangiocarcinoma and be treated promptly by resection and chemotherapy to increase the pa...
Combined hepatocellular carcinoma and cholangiocarcinoma is found at a frequency of 1.0-6.3% in resected primary hepatic tumors. However, the case of double cancers of hepatocellular carcinoma and cholangiocarcinoma that are discovered synchronously in different lobes of a liver is very rare. We experienced a case of a 74-year-old man who was found to have hepatocellular carcinoma and cholangio...
ing a mixture of carcinomatous and sarcomatous elements (1). Liver carcinosarcomas are classified as two types including sarcomatoid hepatocellular carcinoma (HCC) and cholangiocarcinoma. A sarcomatoid HCC is a carcinoma that most resembles a sarcoma found in the liver. Only a few cases of intrahepatic sarcomatoid cholangiocarcinomas have been reported (1-6). To the best of our knowledge, an in...
Unresectable cholangiocarcinoma is poorly responded to chemotherapy, especially for the case refractory to gemcitabine and cisplatin. Here, we tested whether high expression of thymidine phosphorylase (TP) can be a predictive biomarker for the indicator for gemcitabine and doxifluridine combination chemotherapy in the cholangiocarcinoma refractory to gemcitabine and cisplatin. Immunohistochemic...
Seroprevalence of hepatitis virus B seropositive in the patients with cholangiocarcinoma: a summary.
The exact etiology of cholangiocarcinoma remains undetermined. One of the related risk factors for its development might be chronic viral hepatitis infection. Concerning hepatitis B infection, a correlation with cholangiocarcinoma has been documented. Here, we summarize knowledge on the prevalence of hepatitis B seropositivity among patients with cholangiocarcinomas. According to the literature...
Clear-cell cholangiocarcinoma is a very uncommon variant of cholangiocarcinoma with a largely unknown natural history and prognosis. We report a case of a 51-year-old previously healthy woman presenting with a large liver nodule found on routine imaging. Needle biopsy of the lesion suggested a non-hepatocellular carcinoma. After extensive workup for other primary neoplasms, the patient underwen...
Sarcomatoid combined hepatocellular-cholangiocarcinoma is an extremely rare primary hepatic malignancy and only a few cases have been reported. Herein, we report a case of combined hepatocellular-cholangiocarcinoma with sarcomatoid changes in a 52-year-old man, who had a history of liver cirrhosis and transarterial chemoembolization. The resected liver revealed a mass of 4.5×3.5 cm. Microscopic...
Cholangiolocellular carcinoma is a minor primary cancerous tumor of the liver and its coexistence with intrahepatic cholangiocarcinoma in the liver is rare. We herein report a case of concurrent cholangiolocellular carcinoma and intrahepatic cholangiocarcinoma in the liver, in addition to a rectal G1 neuroendocrine tumor, a so-called carcinoid. The intrahepatic tumors showed a different uptake ...
Tauroursodeoxychate (TUDCA) is used for the treatment of cholangiopathies including primary sclerosing cholangitis, which is considered the primary risk factor for cholangiocarcinoma. The effect of TUDCA on cholangiocarcinoma growth is unknown. We evaluated the role of TUDCA in the regulation of growth of the cholangiocarcinoma cell line Mz-ChA-1. TUDCA inhibited the growth of Mz-ChA-1 cells in...
