Exaggerated placental site, abbreviated EPS, is an uncommon benign pathology that is a gestational trophoblastic disease.

It was previously known as syncytial endometritis.^[1]

Definition:

Note:

Used to go by a terrible old term: syncytial endometritis:^[2]
- Not syncytial -- mostly.
- Not inflammatory.

Features:^[2]

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.
