Fixation
Generally 10% neutral buffered formalin.
See also: General notes on fixation
Microscopic evaluation
The main objectives are:
- Confirm an endometrioid polyp.
- Look for signs of atypia or malignancy.
Complex hyperplasia without atypia: Cystically dilated endometrial glands lined by a single layer of columnar epithelium.[1]
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.[2]
Reporting
Most importantly:
- Presence or absence of atypia.
Optionally, report the type of epithelium at both the surface and gland coverings.
