Category:Liver, Primary Tumours

Primary tumours are not as common as secondary tumours. They may arise from each of the four main tissues within the liver, liver parenchymal cells (hepatoma, liver cell carcinoma), bile ducts (cholangioma, bile duct carcinoma), blood vessels (haemangioma, haemangiosarcoma), connective tissue (fibroma, sarcoma). NB: Liver cell tumours and malignant bile duct tumours are the two most common primary hepatic neoplasms. Liver cell tumours are usually seen as discrete masses within the liver parenchyma. The tumour tissue is usually reddish brown in colour. It can be malignant, metastases occuring to the local lymph nodes and lungs.
