Basal cell hyperplasia of the prostate
From Libre Pathology
|Basal cell hyperplasia of the prostate|
|Diagnosis in short|
Basal cell hyperplasia of prostate. H&E stain. (WC)
|LM||low power gland architecture near normal, glands usually not as small as cancer, usu. lack nuclear hyperchromasia, two cell populations (as in normal prostate glands), basal cells may have nucleoli|
|LM DDx||urothelial metaplasia, prostate carcinoma|
|IHC||basal presents (p63 +ve, CK34betaE12 +ve)|
|Other||incidental microscopic finding|
- Benign lesion that can be misdiagnosed as cancer.
- Low power gland architecture near normal.
- 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.
- 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.
- Urothelial metaplasia of the prostate - larger cells, cell borders seen.
- Usually not reported.
