Abstract
Endometrial hyperplasia (EH) is a spectrum of morphological changes ranging from a slightly disordered pattern seen in the late proliferative phase of the menstrual cycle to the irregular proliferation of the endometrial glands with an increase in gland-to-stroma ratio leading to thickening of the endometrium. It encompasses histological subtle and spontaneously reversible proliferative lesions to emerging endometrial carcinoma. As endometrial hyperplasia is the only known direct precursor of endometrial carcinoma, sensitive and accurate diagnosis can reduce the likelihood of development of invasive endometrial carcinoma. Currently, two classifications are in use: the World Health Organization (WHO) 2014 classification and the endometrial intraepithelial neoplasia (EIN) classification. The optimal management of endometrial hyperplasia is the subject of significant debate. Regression of hyperplasia to normal endometrium represents the key to conservative treatment of endometrial hyperplasia. In younger women who desire fertility, medical treatment with progestin is appropriate with extremely close monitoring. In older women who do not wish to retain their uterus, hysterectomy is the treatment of choice. In this chapter, a brief overview of the development of a current understanding of EH will serve to understand their diagnosis and management.
