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
Main article: Prostate_carcinoma#General
- Rare.
- Usually low grade, i.e. Gleason score 6/10.[1]
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.
Note:
- Prominent nucleoli usually infrequent or absent![1]
- Can be thought of as pseudohyperplastic adenocarcinoma without the nucleoli.
