Definition / general
  • Variant with fibrous septa separating trabecular cell plates but no lamellar fibrosis
  • Also called scirrhous carcinoma
  • May not be a distinct histopathologic entity
Clinical features
  • 1 - 4% of all hepatocellular carcinoma
  • Associated with hypercalcemia and hypophosphatemia but not with bone metastases
  • Better prognosis (Hepatogastroenterology 2009;56:1086)
Gross description
  • Single, subcapsular, unencapsulated, large, lobulated, gray white, firm, circumscribed mass, often with serrated border
  • Often satellite nodules
  • More diffuse fibrosis than fibrolamellar variant, no radiating fibrous bands, no central scar and usually no cirrhosis
  • Cirrhosis usually similar to classic HCC
Microscopic (histologic) description
  • Fibrous septa separate trabecular cell plates but no lamellar fibrosis
  • Cell plates 3 or more cells thick
  • Tumor cells may have pseudoglandular (acinar) features compared to fibrolamellar variant, are smaller, lack vesicular nuclei and prominent nucleoli and have less abundant and granular cytoplasm
  • No apparent endothelial sinusoidal cells
