Cystic Endometrial Hyperplasia.

Cystic Endometrial Hyperplasia.
Cystic endometrial hyperplasia may develop after chronic exposure to estrogens such as phytoestrogens or estrogenic implants. It may also be a sequela to chronic cystic follicular degeneration or granulosa cell tumors. In this slaughterhouse specimen, the right horn has been opened to show the hyperplastic endometrial cysts and some inspissated secretions.
