Micro Description
  • Abundant xanthomatous cytoplasm, small hyperchromatic nuclei, minimal / no atypia, pink luminal secretions

  • Cytoplasm differs between malignant and benign glands
  • No obvious basal layer compared to normal glands
  • Foamy morphology comprises most of cancer
  • Usually Gleason score 3+3=6, occasionally Gleason 7 or higher (Am J Surg Pathol 2009;33:583)
