Features:<ref name=Ref_PBoD1080>{{Ref PBoD|1080 and 1082}}</ref>
*Proliferative type endometrium with:
**Cystic dilation of glands focally that do not have (glandular) secretions - '''key feature'''.
***Glands >2x normal size - usually 3-4x normal.
***Irregular shape, e.g. gland contour has inflection points.
***Greater than fours glands involved (dilated).
*+/-Stromal condensation -- balls of stromal tissue, aka "blue balls" (due to breakdown of endometrium).
 
Notes:
*Dilated glands often have tubal metaplasia.{{fact}}
*Eosinophilic syncytial metaplasia - common.
**Features: abundant eosinophilic cytoplasm, mild nuclear atypia +/-loss of nuclear stratification, no mitoses).
 
DDx:
*[[Proliferative phase endometrium]].
**Glands: straight, tubular, tall pseudostratified columnar cells, mitotic figures, no vacuolation, no mucus secretion, abundant mitoses.
**Stroma: cellular, stroma (spindle cells), mitoses.
*[[Simple endometrial hyperplasia]] without atypia - architectural atypia diffuse.
*[[Benign endometrial polyp]].

ENDOMETRIUM, BIOPSY:
- COMPATIBLE WITH DISORDERED PROLIFERATIVE ENDOMETRIUM (FRAGMENTS OF PROLIFERATIVE
  ENDOMETRIUM WITH EVIDENCE OF SHEDDING AND VERY RARE GLAND DILATION).
- VERY SCANT STRIPPED ENDOCERVICAL EPITHELIUM WITHOUT APPARENT PATHOLOGY.
- NEGATIVE FOR ENDOMETRIAL HYPERPLASIA.
- NEGATIVE FOR MALIGNANCY.

<pre>
ENDOMETRIUM, CURETTAGE:
- PROLIFERATIVE ENDOMETRIUM, FOCALLY WITH GLAND DILATION AND SMALL BLOOD
  VESSELS, SEE COMMENT.
- NEGATIVE FOR HYPERPLASIA AND NEGATIVE FOR MALIGNANCY.
 
COMMENT:
A fibrotic stroma is not present. The findings may represent a remnant of the previously
excised endometrial polyp or disordered proliferative endometrium. Follow-up is suggested.
</pre>
 
====Micro====
The sections show a well-sampled endometrium. Mitotic figures are identified within the
glands and stroma. Irregular, moderately enlarged glands are seen (only) in one of several
fragments; most of the endometrial glands are round, regular and small.
 
No stromal condensation is apparent. No secretions are in the glands.
 
There are no back-to-back glands. No nuclear atypia is apparent. No thick-walled blood
vessels are apparent.
