Template:Endometrial hyperplasia, atypia and/or malignancy
Endometrial hyperplasia: Cystically dilated endometrial glands lined by a single layer of columnar epithelium, without atypia.[1]
Endometrial intraepithelial neoplasia (EIN), has the following criteria:[2]
- Architectural gland crowding
- Altered cytology relative to background glands
- Minimum size of 1 mm
- Exclusion of adenocarcinoma
- Exclusion of mimics
Mitoses should also preferably be seen.Endometrial adenocarcinoma[3], most commonly endometrioid, in which case low-grade carcinoma is distinguished from hyperplasia with atypia by the presence of glandular crowding with endometrial stromal exclusion, and significant cribriform, confluent glandular, labyrinthine, papillary/villoglandular, or non-squamous solid architecture.[4]
