  • Tumor cells with polygonal shape are arranged in nests, tubules and papillae.
  • They have bright cytoplasm and well presented cell membrane. The light cytoplasm is due to extraction of lipids and glycogen from their cytoplasm.
  • Tumor cells infiltrate walls of blood vessels.
  • Among tumor are found necroses and hemorrhages.
  • Stroma is scant, with thin-wall blood vessels and scant lymphoid infiltrations.
  • Tumor is well distinguished with  a pseudocapsule (PsC): thick fibrous connective tissue, which at some places appear to have neoplastic infiltration.
