  • Endometrial hyperplasia without atypia is a proliferation of endometrial glands of irregular size and shape without significant cytological atypia.

- endometrial atypical hyperplasia / endometrioid intraepithelial neoplasia (EAH/EIN)

  • Endometrial atypical hyperplasia / endometrioid intraepithelial neoplasia (EAH/EIN) is simultaneous change of epithelial cytology and an increased number of endometrial glands in comparison with the stroma (crowded gland architecture) within a morphologically defined region, distinct from the surrounding endometrium or from entrapped normal glands.
