Histopathologic and cytopathologic images.
(A) proliferative endometrium (Left: HE × 400) and proliferative endometrial cells (Right: HE × 100)
(B) secretory endometrium (Left: HE × 10) and secretory endometrial cells (Right: HE × 10)
(C) atrophic endometrium (Left: HE × 10) and atrophic endometrial cells (Right: HE × 10)
(D) mixed endometrium (Left: HE × 10) and mixed endometrial cells (Right: HE × 10)
(E): endometrial atypical hyperplasia (Left: HE × 10) and endometrial atypical cells (Right: HE × 200)
(F) endometrial carcinoma (Left: HE × 400) and endometrial cancer cells (Right: HE × 400).
The main objectives are:
- Confirm an endometrioid polyp.
- Look for signs of atypia or malignancy.
Non-complex endometrial polyp without atypia, with a thick-walled blood vessel in middle.
Non-complex endometrial polyp without atypia, with tubal metaplasia (black arrow) and a thick-walled blood vessel (white arrow). The stroma is hemorrhagic.
Complex hyperplasia without atypia: Cystically dilated endometrial glands lined by a single layer of columnar epithelium
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.
