Cystic Endometrial Hyperplasia.
Cystic endometrial hyperplasia may develop after chronic exposure to estrogens such as phytoestrogens or estrogenic implants. It may also be a sequella to chronic cystic follicular degeneration or granulosa cell tumors. In this slaughterhouse specimen a fully developed corpus luteum is present on the right ovary.
