Note: Distinction must be made between all hepatic tumours and [[Liver Unknown Aetiology - Pathology #Nodular hyperplasia|benign nodular hyperplasia]] that is frequently observed in the older canine. The most significant primary tumours in the dog are hepatomas, [[Liver Proliferative - Pathology #Hepatocytic|Hepatocellular]] and [[Liver Proliferative - Pathology #Cholangiocellular|Cholangiocellular]] carcinomas and hepatic carcinoids. [[Liver Proliferative - Pathology #Hepatocytic|Hepatocellular carcinoma]] and  [[Liver Proliferative - Pathology #Cholangiocellular|Cholangiocellular carcinoma]] are the most significant in cats.
