Pathology of Endometrial Carcinoma
Pathology of Endometrial Carcinoma
- NE
NE of Endometrial Carcinoma
- Site
- Focal
- Diffuse lining the endometrium.
NE of Endometrial Carcinoma
- Shape
- Pale friable and necrotic sessile.
- Pedunculated mass.
NE of Endometrial Carcinoma
- Size
- Limited to the endometrium
- Invading the myometrium & serosa
ME of Endometrial Carcinoma
Spread of Endometrial Carcinoma
Spread of Endometrial Carcinoma
- Remains Limited ……
- Remain limited to endometrium for long time and acts as a surface rider due to presence of glycoprotein layer preventing penetration.
Spread of Endometrial Carcinoma
- Local
Most important
- To myometrium.
- To the cervix, vagina, tubes ovaries …. etc.
Spread of Endometrial Carcinoma
- Lymphatic
Late as endometrium is poor in lymphatics
- Main LNs are internal iliac LNs and common iliac lymph nodes, then to para-aortic nodes.
Spread of Endometrial Carcinoma
- Blood
Rare
Spread of Endometrial Carcinoma
- Special Route
Trans-cavitary and implantation spread.
Staging of Endometrial Carcinoma
Staging of Endometrial Carcinoma
- Stage I
Confined to uterine corpus and ovary
