Anovulatory endometrium, abbreviated AE, is common perimenopausal finding. It is a diagnosis that is inferred from the clinical context.

General

  • Individuals usually perimenopausal.

Relation to disordered proliferative endometrium

Some consider disordered proliferative endometrium (DPE) a synonym for anovulatory endometrium.[1]

Libre Pathology separates the two. DPE has prominent gland dilation (reminiscent of simple endometrial hyperplasia) and may not have shedding. AE has shedding without gland dilation.

Microscopic

Features:

  • Shedding:
    • Stromal condensation.
    • Apoptotic endometrial epithelium.
  • Weakly proliferative glands or non-proliferative glands.
