Definition / general
Microscopic (histologic) description
  • Abundant xanthomatous cytoplasm, small hyperchromatic nuclei, minimal / no atypia, pink luminal secretions
  • Hyperchromatic nuclei may make nucleoli difficult to see
  • 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)
  • Needle biopsies may have only a few atypical foamy glands (Ann Diagn Pathol 2008;12:349)
