Basal cell hyperplasia of the prostate, also known as basal cell hyperplasia, is a benign change of the prostate gland that may be misdiagnosed as prostate carcinoma.
General
- Benign lesion that can be misdiagnosed as cancer.[1]
Microscopic
Features:[2]
- Low power gland architecture near normal.[3][4]
- Glands not as small as cancer.
- Folds in gland lumina.
- No nuclear hyperchromasia.
- Two cell populations (as in normal prostate glands).
- Basal cells may have nucleoli.
DDx:
- High-grade prostatic intraepithelial neoplasia - has nuclear hyperchromasia, architecture usually different (micropapillary, tufted, cribriform or flat).
- Prostatic adenocarcinoma.
- Adenoid cystic/basal cell carcinoma of the prostate - for the adenoid cystic-like pattern of BCH.[5]
- Urothelial metaplasia of the prostate - larger cells, cell borders seen.
