Endometrial Hyperplasia and Related Cellular Changes

  • Robert J. Kurman
  • Henry J. Norris


Endometrial hyperplasia constitutes a heterogeneous group of abnormal proliferations, some of which are precursors of endometrial carcinoma. In the 1970s the role of unopposed estrogenic stimulation in the development of endometrial hyperplasia and carcinoma was firmly established on the basis of case-control studies linking these conditions with exogenous unopposed estrogen replacement therapy.26,28,54,58,72,81 Subsequently, in the 1980s various types of endometrial metaplasia were described.33,34 As the pathological features of both of these lesions became further characterized, their behavior and relationship to endometrial carcinoma have become more clearly delineated.
