Benign prostatic hyperplasia (BPH) is a histopathological diagnosis characterized by epithelial cell & smooth muscle cell proliferation in the transition zone of the prostate leading to a non-malignant enlargement of the gland, which may result in lower urinary tract symptoms, including voiding and storage symptoms.
It is commonly called enlarged prostate.
Etiology is unknown but due to its similarity to the embryonic morphogenesis of the prostate has led to the hypothesis that BPH may be the result of "reawakening" in adulthood of embryonic induction processes.
