'''Complex endometrial hyperplasia''', abbreviated '''CEH''', is a relatively common pre-malignant pathology of the [[endometrium]].
 
It is generally subdivided into '''complex endometrial hyperplasia without atypia''' and '''complex endometrial hyperplasia with atypia'''.
 
==Microscopic==
Features:
*Increase in size & number of glands + irregular shape - '''key feature'''.
*Cell stratification.
*Nuclear enlargement.
*Mitoses common.
*No nuclear atypia.
 
Notes:
*Normal "gland-to-stroma ratio" is 1:3.
*Two "touching" glands may be one gland in section.
 
DDx:
*[[Complex endometrial hyperplasia with atypia]].
*[[Endometrioid endometrial carcinoma]] - see ''[[endometrial carcinoma versus complex endometrial hyperplasia]]''.

[[Squamous morules]] - commonly associated with hyperplasia and malignancy:

===Endometrial carcinoma versus complex endometrial hyperplasia===
Complex endometrial hyperplasia:
*Non-confluent - glands distinct from one another.
 
====Classic criteria for endometrial carcinoma====
This is pimping material that shows up on exams.
 
Endometrial carcinoma has one of the following:<ref name=Ref_GP239>{{Ref GP|239}}</ref><ref name=pmid7074572>{{Cite journal  | last1 = Kurman | first1 = RJ. | last2 = Norris | first2 = HJ. | title = Evaluation of criteria for distinguishing atypical endometrial hyperplasia from well-differentiated carcinoma. | journal = Cancer | volume = 49 | issue = 12 | pages = 2547-59 | month = Jun | year = 1982 | doi =  | PMID = 7074572 }}</ref><ref>URL: [http://www.cap.org/apps/docs/committees/cancer/cancer_protocols/2011/Endometrium_11protocol.pdf http://www.cap.org/apps/docs/committees/cancer/cancer_protocols/2011/Endometrium_11protocol.pdf].

#[[Desmoplastic stromal response]].
#Confluent cribriform growth. †
#Extensive papillary growth. †
#Severe cytologic atypia. †
 
Note:
* † There is a size cut-off for criteria 2, 3 and 4: > 2.1 mm.<ref name=pmid7074572/>
How to remember '''ABCDE''':
*'''A'''typia '''B'''ad.
*'''C'''onfluent cribriform growth.
*[[desmoplasia|'''D'''esmoplasia]].
*'''E'''xtensive papillary growth.

- COMPLEX ENDOMETRIAL HYPERPLASIA.
-- NEGATIVE FOR CYTOLOGIC ATYPIA.

  SQUAMOUS MORULES.
- ENDOMETRIAL POLYP WITH ONE ATYPICAL GLAND AND A SQUAMOUS MORULE.
