Nodular hyperplasia of the prostate gland, also benign prostatic hyperplasia (abbreviated BPH), is a common benign pathology of the prostate gland.
It is also known as prostatic nodular hyperplasia. Occasionally, it is referred to as benign prostatic hypertrophy; this is a misnomer. This pathology is not a hypertrophy.
General
- Very common.
- Incidence increases with age.
Clinical - mnemonic I WISH 2p:[1]
- Intermittency.
- Weak stream.
- Incomplete emptying.
- Straining.
- Hesitancy.
- Post-void dribbling.
- Prolonged voiding.
Others:
- Hematuria - common.[2]
Treatment:
- Medications.
- Transurethral resection of the prostate (TURP).
- Rezum.[3]
- Laser treatment (GreenLight).[4]
Gross
- Enlargement of the prostate.
- Nodularity of the prostate.
Microscopic
Features:
- Stromal and/or glandular hyperplasia.
- Stromal component has small blood vessels.
Notes:
- Should not be diagnosed on core biopsy!
- One series suggests clinically relevant prostate cancer is seen in ~1.5% of resections for BPH.[5]
DDx:
- Urothelial carcinoma - significant nuclear atypia.
- Prostate carcinoma - especially low-grade.
- Prostatic stromal tumour of uncertain malignant potential - lacks small vessels.[6]
