Foamy gland carcinoma, also foamy gland adenocarcinoma,[1] is an uncommon variant of prostate carcinoma that has a bland appearance and may be confused with benign glands.

General

Microscopic

Features:

  • Increased glandular density - key feature.
  • Eosinophilic intraluminal amorphous secretions - key feature.
  • Abundant foamy cytoplasm.
  • Tufted glandular border.
  • Gland size larger than "typical" prostate cancer.
