Overview
Endometrial cancer may be classified according to histology into 7 subtypes: endometrioid, uterine papillary serous, mucinous, clear cell, squamous cell, mixed and undifferentiated.
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
