[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.

[Primary intestinal tuberculosis]. / La tubercolosi intestinale primitiva.

Tuberculosis, with its pulmonary and extrapulmonary localizations, is rapidly increasing in Italy. The authors describe a case of a primary colonic tuberculosis in a 52-year-old Caucasian man. At admission the patient reported a 6-month history of constipation, weight loss and abdominal pain. He had rectal bleeding in the last two weeks. Haematological tests and chest X-ray were negative. Colonoscopy showed a stricture in the proximal transverse colon and multiple ulcers in the ileocecal tract. Multiple biopsies and culture demonstrated tuberculosis. The patient underwent a right hemicolectomy after an episode of acute intestinal hemorrhage and received pharmacological treatment for nine months. After four years he is still free of disease.
