Cholangiocarcinoma*

An association of hepatolithiasis and cholangiocarcinoma is thought to be rare, with a rate reported to be 2.36%-10%. Most of the cholangiocarcinomas concurrent with intrahepatic stones are found in the vicinity of the hepatolithiasis, and the diagnosis of intrahepatic cholangiocarcinoma in cases with hepatolithiasis is very difficult to detect preoperatively in spite of recent developments in techniques of imaging studies. Recently, the development of cholangiocarcinoma was reportd even after the complete removal of the hepatic stones. Thus, bile stasis and bacterial infecton appear to be important causative factors causing cholangiocarcinoma rather than the stone itself. A rare case is reported on intrahepatic cholangiocarcinoma developed in a remote region from the site of the hepatolithiasis. Therefore, the possible presence of cholangiocarcinoma should always be considered and sought during the diagnosis and treatment of hepatolithiasis.

The diagnosis of hilar cholangiocarcinoma (CCA) is usually accomplished through a combination of imaging modalities and endoscopic examination including tissue sampling. Although high quality cross-sectional imagings provide evidences for hilar obstruction and a malignancy arising from the bile duct, a definitive diagnosis and staging often obtained through the use of endoscopic procedures. It can provide complementary information for accurate tumor extension and tissue acquisition for histologic confirmation. These informations are important in determining therapeutic options. However, despite the various available techniques, the diagnosis and accurate staging of hilar CCA is often still challenging. Newly developed adjunctive diagnostic endoscopic techniques including intraductal ultrasound and cholangioscopy improve the accuracy of endoscopic diagnosis of this lesion. Multiple endoscopic modalities can be tried to obtain accurate assessment of the tumor. Therefore, endoscopy will continue to occupy an important position in assessment of the hilar CCA.

Rhabdoid transformation is an extremely rare occurrence in sarcomatoid cholangiocarcinoma. Only two cases have been reported in the medical literature worldwide, and its clinical and pathological characteristics remain unknown. Published case reports indicate that rhabdoid cholangiocarcinoma grows rapidly, with early metastasis and a particularly poor prognosis. Here, we report a case of rhabdoid transformation in sarcomatoid cholangiocarcinoma that exhibited aggressive behavior and resulted in a devastating prognosis.

Introduction: We report a case of intrahepatic cholangiocarcinoma and portal hypertension developing in a liver with biliary microhamartomas (von Meyenburg’s complex). Case Report: The patient was a 55-year-old man who had a past medical history of diffuse multiple liver abscesses. During follow-up examination, a hypovascular nodule measuring 2.1 cm in diameter was incidentally found in segment 8 of the liver. Surgical resection was performed based on a suspected diagnosis of hepatocellular carcinoma. A gastrofiberscopy examination detected characteristic findings of portal hypertensive gastropathy. During the laparotomy, multiple tiny cystic lesions were observed in a diffuse pattern across the liver surface. The liver parenchyma was slightly fibrotic and haemorrhagic. A histopathological examination revealed intrahepatic cholangiocarcinoma with vascular invasions in von Meyenburg’s complex. Multiple biliary adenomas were also observed among the biliary microhamartomas adjacent to the main tumour, suggesting that the malignant transformation of the biliary adenomas might have been responsible for the development of the intrahepatic cholangiocarcinoma. The histopathologic examination also revealed sinusoidal dilation and abnormal spacing of the portal tracts and central veins as evidence of portal hypertension.

Cholangiocarcinoma is the second most common hepatobiliary malignancy. Histopathologically, it usually appears as a differentiated tubular adenocarcinoma. It shows a strong tendency toward early regional spread. Cutaneous metastases of cholangiocarcinoma are rare although distant hematogenous metastases may be observed during the late stages. We report a case of cutaneous metastasis of cholangiocarcinoma, presenting as a solitary asymptomatic firm nodule on right upper lip.
