==Simple endometrial hyperplasia==
*[[AKA]] ''simple hyperplasia''.
*[[AKA]] ''simple hyperplasia''.
===General===
{{Main|Simple endometrial hyperplasia}}
*More common than simple endometrial hyperplasia with atypia.
*Very low risk for progressing to [[endometrioid endometrial carcinoma]].
 
===Microscopic===
Features:<ref name=Ref_GP236>{{Ref GP|236}}</ref>
*Irregular dilated glands (with large lumens) - '''key feature'''.
**Glands described as "animal shapes".
*Variation of gland size.
*No nuclear atypia.
**Uniform columnar nuclei.
*Normal gland density (gland area in plane of section/total area ~= 1/3).
 
DDx:
*[[Disordered proliferative phase]].
*[[Complex endometrial hyperplasia]] - has increased gland-to-stroma ratio.
*[[Atrophic endometrium|Cystic atrophy of the endometrium]] - does not have proliferative activity.<ref name=pmid16873562>{{Cite journal  | last1 = McCluggage | first1 = WG. | title = My approach to the interpretation of endometrial biopsies and curettings. | journal = J Clin Pathol | volume = 59 | issue = 8 | pages = 801-12 | month = Aug | year = 2006 | doi = 10.1136/jcp.2005.029702 | PMID = 16873562 | PMC = 1860448 }}</ref>
