Presentations
Hepatocellular carcinoma is the most common diagnosis for liver tumors.:[1]
Microscopic evaluation
Hepatocellular carcinoma typically displays:[2]
- Trabecular pattern surrounded by layer of flattened endothelial cells.
- Presence of sinusoidal vessels surrounding tumor cells
- Scant stroma, and minimal desmoplasia
- Polygonal cells with distinct cell membranes
- Abundant granular eosinophilic cytoplasm
- Nuclei with increased N/C ratio, round nuclei with coarse chromatin and thickened nuclear membrane, and may have prominent nucleoli.
- Steatotic hepatocellular carcinoma is a common variant, found most commonly in small, well-differentiated tumors.[3]
Differentiation
Differentiations of hepatocellular carcinoma are:[2]
- Well differentiated:
- Thin plates (1 - 3 hepatocytes thick)
- Hepatocytes are smaller than normal
- Abnormal reticulin network
- Minimal nuclear atypia
- Nuclear density of 2x compared to normal liver
- Moderately differentiated:
- Trabecular pattern at least 4 cells thick
- Larger cells with more eosinophilic cytoplasm
- Distinct nucleoli
- Pseudoglands
- Poorly differentiated:
- Large tumor cells with hyperchromatic nuclei in compact growth pattern
- Rare trabeculae or bile
- Prominent pleomorphism
- May have spindle cell or small cell areas
