A case of cholangiocarcinoma in a two-year-old Ring-Necked Pheasant (Phasianus colchicus) is reported. The liver was enlarged and numerous white foci were seen in the liver parenchyma. Histopathologically, channels with or without lumens and separated from one another by thin connective tissue septa were observed. Tumour cells were strongly positive for cytokeratin, Ki-67 and proliferative cell nuclear antigen. This is the first report of colangiocarcinoma in pheasants.Keywords:
