Tumors arising from intrahepatic bile ducts and gall bladder have been described in several species of domestic animals. Cholangiocarcinoma is a neoplastic proliferation of the intrahepatic biliary system commonly reported in dogs, cats, sheep, cattle, horses, goat, birds kept in captivity, and occasionaly in wildlife animals. A few cases have been described in broiler chicken. This is the first report of cholangiocarcinoma in poultry, species Gallus gallus domesticus, in Brazil. The diagnosis was based in histology lesions and immunohistochemistry findings.(AU)
