• The neoplastic glands are crowded.
• The epithelium contains scattered neutrophils.
• The nuclei ahve chromatin clumping and clearing.
• Nucleoli are visible.
• The N:C is increased.
• The cells are not oriented to the lumen.
•associated with unopposed estrogen use
•may be exogenous (non-cycled estrogens) but generally
•endogenous due to peripheral aromatization of adrenal
androgens by adipose in obese women
•also associated with granulosa cell tumors and other estrogen producing ovarian tumors as well as polycystic ovary

evidence of hyperestrinism
•estrogen drives continued proliferation
acquisition of somatic mutations

•post-menopausal bleeding is usual symptom;
symptoms rare and may indicate advanced disease
•most patients are Stage I (confined to endometrium) at
diagnosis and respond completely to hysterectomy
•neoplasm spreads to cervix, deep into myometrium, to ovary,
regional lymph nodes and then to distant sites
