What is regenerative hepatocellular nodules
Proliferation of hepatocytes in response to loss of hepatocytes
This process is accompanied by fibrosis and disruption of architecture
Biliary Adenomatous Hyperplasia Eimeria stiedae - rabbit
Hepatocellular nodular hyperplasia
What do hepatocellular adenomas cause
Well rounded red/brown nodules
- Well differentiated hepatocytes
- Compresses adjacent parenchyma
What are hepatocellular carcinomas
Malignant
Often large, friable, irregular masses

Describe the pathology pf cystic mucinous hyperplasia
- External surface of gallbladder appears normals
- Internal surface is grey/white, thickened and spongy
