	~~#redirect~~ [[~~Gestational_trophoblastic_disease#Exaggerated_placental_site~~]]		'''Exaggerated placental site''', abbreviated '''EPS''', is an uncommon benign pathology that is a
			[[gestational trophoblastic disease]].

			It was previously known as '''syncytial endometritis'''.<ref>URL: [http://www.webpathology.com/image.asp?case=565&n=7 http://www.webpathology.com/image.asp?case=565&n=7]. Accessed on: 22 May 2014.</ref>

			==General==
			*Benign.

			Definition:
			*"Increased number" of implantation-site [[Intermediate trophoblast\|intermediate trophoblastic cells]].

			Note:
			*Used to go by a terrible old term: ''syncytial endometritis'':<ref name=ouhsc_kfung>URL: [http://moon.ouhsc.edu/kfung/IACP-OLP/TC-Text/TC-01-Supp.pdf http://moon.ouhsc.edu/kfung/IACP-OLP/TC-Text/TC-01-Supp.pdf]. Accessed on: 15 August 2011.</ref>
			**Not syncytial -- mostly.
			**Not inflammatory.

			Features:<ref name=ouhsc_kfung/>
			*Intermediate trophoblast:
			**Abundant (eosinophilic) cytoplasm.
			*Usu. adjacent to:
			**[[Chorionic villi]].
			**Decidua - endometrial stromal cells with a nucleus central, eosinphilic cytoplasm, well-defined cell borders.
			*No mitotic activity.
			*Ectatic blood vessels.
