[Intrahepatic cholangiocarcinoma: case report]. / Colangiocarcinoma intraepatico: case report.

The primitive tumors of the liver are relatively rare in the Western countries (around the 0.7% of all the neoplasms) while they present more elevated incidence in Africa and in the South Asian East. While the hepatocellular carcinoma rises up in the 50-70% of the cases in livers cirrosis, this correlation is not valid for the form of carcinoma to departure from the learned intra and extra biliar. The etiology of the intrahepatic colangiocarcinoma (CC) stays unknown. They have stayed observe, on the other hand, of the conditions sometimes correlated to the development of the CC (Carolí morbs, ulcerative colitis, asbestosis). The CC usually rises up from the epithelial cells of surface that delimit the biliary ducts, although different studies suggest that these tumors can also originate from the learned smaller biliary ducts, from the hepatic cysts of the policistic illness and from the complexes of von Meyenburg. The low incidence of the CC, the clinical atypical debut, the not facility of a precise diagnosis have aroused our interest so that the present job wants to be a modest scientific contribution to this type of pathology.

[Intrahepatic biliary cystadenoma: case report]. / Cistoadenoma biliare intraepatico: case report.

According to the OMS classification of the epithelial benign neoplasm of the liver, the adenomas represent the most important group. In literature an increase of their incidence in the last years is reported especially in the female sex, in relationship to the diffusion of the use of hormonal contraceptives. The biliar cistoadenoma (BCA) represents a not frequent neoplasm of the liver that has origin on the inside of the liver, and less frequently from the extrahepatic biliar system. The surgical interest is underlined by the potentiality of the malignant evolution of the lesion and by its high tendency to the relapse. The real difficulty is represented by differential diagnosis from the other cystic lesions of the liver and by the need of its radical excision and therefore of real hepatectomy.
