Primary hepatic tumours are rare, however, the liver is a common site of metastatic tumours due to the rich blood supply (hapatic portal vein and hepatic artery). Malignant primary tumours include:
- Hepatocellular carcinoma
- Cholangiocellular carcinoma
- Gall bladder carcinoma
- Haemangiosarcoma
- Mast cell tumour
- Hepatic carcinoids
Benign tumours include:
- Hepatocellular adenoma (hepatoma)
- Cholangiocellular adenoma
- Gall bladder adenoma
Note: Distinction must be made between all hepatic tumours and benign nodular hyperplasia frequently observed in the canine. The most significant primary tumours in the dog are hepatomas, hepatocellular and cholangiocellular carcinomas and hepatic carcinoids. Hepatocellular carcinomas and cholangiocarcinomas are the most significant in cats.
Signalment
- Hepatic carcinoma occurs most often in male dogs over 10 years old
- Cholangiocellular carcinoma occurs more commonly in female cats
Description
Carcinogens and toxins for example nitrosamines can induce hepatic tumours in an experimental environment.
