Overview
Classification
- Endometrial cancers are classified in one of the following two categories:
- Type 1 may arise from complex atypical hyperplasia and is pathogenetically linked to unopposed estrogenic stimulation.
- Type 2 develops from atrophic endometrium and is not linked to hormonally driven pathogenesis.
Cellular Classification of Endometrial Cancer
- 1. Endometrioid (75%–80%).[The most common endometrial cancer cell type is endometrioid adenocarcinoma, which is composed of malignant glandular epithelial elements]
- Ciliated adenocarcinoma.
- Secretory adenocarcinoma.
- Papillary or villoglandular.
- Adenocarcinoma with squamous differentiation.
- Adenoacanthoma.
- Adenosquamous.[Adenosquamous tumors contain malignant elements of both glandular and squamous epithelium]
- 2. Uterine papillary serous (<10%).
- 3. Mucinous (1%).
- 4. Clear cell (4%).
- 5. Squamous cell (<1%).
- 6. Mixed (10%).
- 7. Undifferentiated
-
Endometrial stromal sarcoma
-
Malignant mixed müllerian tumor
