# | '''Secretory phase endometrium''', abbreviated '''SPE''', is a common diagnosis is [[endometrium|endometrial]] specimens. | ||
==General== | |||
*Secretory phase = luteal phase. | |||
**Gynecologists prefer the ovarian descriptor, i.e. ''luteal phase''; pathologists go by what they see, i.e. ''Secretions'' in the (endometrial) glands. | |||
==Gross== | |||
*Thickened endometrium. | |||
==Microscopic== | |||
===Early secretory phase=== | |||
Features - post-ovulatory day 1-5:<ref name=Ref_DCHH237>{{Ref DCHH|237}}</ref> | |||
*Glands: secretory vacuoles. | |||
**First basal to the epithelial nuclei (infranuclear vacuoles). | |||
**Then apical to the epithelial nuclei (supranuclear vacuoles). | |||
*Mitoses may be present - common when vacuoles are subnuclear. | |||
===Mid secretory phase=== | |||
Features - post-ovulatory day 6-8:<ref name=Ref_DCHH237>{{Ref DCHH|237}}</ref> | |||
*Glands: Mucus in glands. | |||
*Stroma: Edema (empty space around the glands). | |||
===Late secretory phase=== | |||
Features - post-ovulatory day 9-12:<ref name=Ref_DCHH237>{{Ref DCHH|237}}</ref> | |||
*Stroma: | |||
**Spiral arterioles. | |||
**Predecidual changes -- mnemonic ''NEW'': | |||
**#Nucleus central. | |||
**#Eosinophilic cytoplasm '''key feature''' (may be subtle to the novice). | |||
**#Well-defined cell borders. | |||
===Premenstrual=== | |||
*Stroma: [[neutrophil]]s, scattered lymphocytes, stromal balls ("blue balls"); "stromal condensation". | |||
*Glands: [[apoptosis]] at the base of the gland.<ref>TC. 22 June 2009.</ref> | |||
Notes: | |||
*Stromal condensation (stromal balls) - premenstrual - stromal cells tightly packed together; nuclei molded together like in small cell tumours.<ref>GAG. 6 Oct 2009.</ref> | |||
*Gland-to-stroma ratio is increased in late secretory phase and menstruation.<ref>URL: [http://www.pathologyoutlines.com/topic/uteruspatternapproach.html http://www.pathologyoutlines.com/topic/uteruspatternapproach.html]. Accessed on: 6 December 2012.</ref> | |||
*Endocervical epithelium (ECE) has a morphology similar to the epithelium of secretory phase endometrium (SPE): | |||
**ECE - grey foamy appearing cytoplasm. | |||
**SPE - eosinophilic cytoplasm. | |||
***Most useful feature to differentiate ECE and SPE is the accompanying stroma. | |||

*[[Endometrial hyperplasia with secretory changes]]. | |||
*[[Endometrium with hormonal changes]]. | |||
*[[Proliferative phase endometrium]] - may have some changes of secretory endometrium; <50% of glands have subnuclear vacuoles ''or'' <50% of cells in the glands have subnuclear vacuoles.<ref name=Ref_EMB14>{{Ref EMB|14}}</ref> | |||

The sections show endometrium with a normal gland-to-stroma ratio. The glands are mildly dilated, tortuous and have mucous with in them. The glandular epithelium is simple and non-pseudostratified. The stroma is edematous and has a decidual reaction. No mitotic activity is apparent. | |||
