Overview
On microscopic histopathological analysis, large polygonal tumours cells with graunular eosinophilic cytoplasm or layered dense collagen bundles are characteristic findings of hepatocellular carcinoma.
Gross Pathology
- Nodular or diffusely infiltrative
- The nodular type may be unifocal (large mass) or multifocal (when developed as a complication of cirrhosis). Tumor nodules are round to oval, grey or green (if the tumor produces bile), well circumscribed but not encapsulated
- Tumours are multifocal in approx. 50% of cases; some authors have suggested it is upto 75% of cases
- The diffuse type is poorly circumscribed and infiltrates the portal veins, or the hepatic veins (rarely)
- Pale in relation to surrounding liver or green (due to bile secretion)
-
Hepatocelluler carcinoma. The image shows a longitudinal slice taken through the full length of the liver.

The tumor is at the top, cirrhotic liver at the bottom, and a fibrous reaction in between. Hepatocellular carcinomas can have a variety of gross patterns, including multinodular / multifocal, such as this one.

Microscopic Pathology
- Large polygonal tumours cells with:
- Graunular eosinophilic cytoplasm
- Low NC ratio
- Layered dense collagen bundles [1]
