Endometrial polyp and intra-epithelial neoplasia. The uterus of this 67-year-old woman treated for 10Â years with conjugated estrogens displays a large polyp covered by a mucosa showing simple (glandulo-cystic) hyperplasia (panel A). An endometrial intra-epithelial neoplasia (EIN) developed in the surrounding mucosa, without any connection to the polyp. Compare the hypertrophic cells lining the neoplastic glands with the normal cells in the residual atrophic gland (panel B)
