Overview
Pathophysiology
Pathogenesis
- Endometrial hyperplasia is a condition of excessive proliferation of the endometrial cells (inner lining of the uterus) associated with an increased gland to stroma ratio.
- The proliferative phase is the second phase in normal mentrual cycle when estrogen causes the lining of the uterus to proliferate. As the ovarian follicles mature, they begin to secrete increasing amounts of estradiol, and estrogen. The estrogens initiate the formation of a new layer of endometrium in the uterus, histologically identified as the proliferative endometrium.[1]
- The majority of cases of endometrial hyperplasia result from high concentrations of estrogen combined with insufficient concentration of the progesterone-like hormones which normally counteract the proliferative effects of estrogen on the endometrial tissue.[2]
- Unopposed oestrogen stimulation (either from an endogenous or exogenous source) is implicated in its pathogenesis
