Overview
Endometrial hyperplasia may be broadly classified based on histology into simple and complex types. Endometrial hyperplasia may also be classified based on the presence or absence of cellular atypia (hyperplasia with cellular atypia and hyperplasia without cellular atypia).[1][2]

The New WHO Classification ()
- The new WHO classification has been simplified for clinical practice, particularly when making treatment choices.
Until the new classification comes into general use it would be useful if histological findings include both the new and the previous WHO classification
- Endometrial hyperplasia may be classified according to new WHO classification (1994) into:
- Hyperplasia without atypia
- Atypical hyperplasia/endometrioid intraepithelial neoplasia
The Endometrial Intraepithelial Neoplasia (EIN) Classification
