Fixation
Generally 10% neutral buffered formalin.

Hysterectomy sampling
A regular hysterectomy grossing is performed, but with the following sampling:[1]
- 2 longitudinal sections through ecto/endocervix (1 anterior and 1 posterior)
- 2 longitudinal sections through upper endocervix/lower uterine segment (1 anterior and 1 posterior), immediately adjacent to the sections taken from the cervix
- 4 full-thickness representative sections of endomyometrium (2 anterior and 2 posterior)
- Transversely section the remaining anterior and posterior endomyometrium (~1 cm thick). Submit the entire endometrium from the lower uterine segment to the fundus, maintaining orientation.
- Submit entire fimbriae (longitudinally sectioned) and 2 representative cross-sections on each side.
Microscopic evaluation
- Look for signs of atypia or malignancy.
Complex hyperplasia without atypia: Cystically dilated endometrial glands lined by a single layer of columnar epithelium.[2]
Complex hyperplasia with atypia: Closely packed endometrial glands with sparse intervening stroma and stratification of the lining epithelium. Epithelial cells show cytological atypia with high nucleocytoplasmic ratio, irregular clumping of nuclear chromatin, and mitotic figures.[3]
Reporting
Most importantly:
- Presence or absence of atypia.
