Notes:
- BPH arises almost exclusively in the transitional and periurethral zones of the gland.
- Stromal proliferation usually predominates in BPH.
- I once viewed a prosected cadaver with a prostate that had grown into the bladder.
- Remember: The term ěhypertrophyî usually refers to an increase in the size of cells. ěHyperplasiaî refers to an increase in the number of cells. Thus, in the case of the prostate, while the entire gland might hypertrophy, or get larger, the cells themselves are not larger, but simply more numerous. You will see BPH called Benign Prostatic Hyperplasia and Hypertrophy.
