Persistent failure of ovulation
Polycystic Ovaries (stein - leventhal syndrome)
Therapy with exogenous oestrogens

List the three old classifications of Endometrium Hyperplasia
And the two new
Simple Hyperplasia
Complex Hyperplasia
Atypical Hyperplasia
Benign or Nonatypical
Endometrial Intraepithelial Neoplasia EIN
What is the percentage chance that Simple Hyperplasia progresses into endometrial adenocarcinoma
1%
What glandular changes are seen in Simple Hyperplasia
Glandular and Stromal proliferation
Glands become elongated and cystically dilated
What cause the glandular changes that are seen in Simple Hyperplasia
Oestrogen stimulation
Is there cellular Atypia present in Endometrium Simple Hyperplasia
Nope
What glandular changes are seen in Endometrium Complex Hyperplasia
Marked proliferation of glands -
Crowding, touching, budding and branching
Describe the lining epithelium in Endometrium Complex Hyperplasia
Hyperplastic
Is there cellular atypia in Endometrium Complex Hyperplasia
No significant
What is the risk of progression of Endometrium Complex Hyperplasia to Endometrial Adenocarcinoma
3-10%
Is Cellular Atypia present in Endometrium Atypical Hyperplasia
Yes
What is the chance of progression of Endometrium Atypical Hyperplasia to Endometrial Adenocarcinoma
20-30%
Define a Benign or Nonatypical Hyperplasia
It is equivalent to Hyperplasia without atypia ; low risk for Carcinoma
