Microscopic evaluation

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.

Reporting

Most importantly:

  • Presence or absence of atypia.

Optionally, report the type of epithelium at both the surface and gland coverings.
