Overview
Ovarian epithelial tumors can be classified on several bases depending on the morphology, histopathological behavior and clinical characteristics. The general classification of benign, borderline and malignant tumors is supplemented by classifications systems augmented by molecular and clinicopathological behavior of the tumors. This section also contains WHO classification of ovarian tumors to allow differentiation between epithelial tumors and other ovarian tumors.
Classification
General Classification
- Epithelial ovarian tumors can broadly be classified on the bases of histopathology and clinical behavior as:[1][2][3][4][5][6]
- Benign
- Borderline
- Malignant tumors
- Table below provides a summary of this classification:
| Epithelial ovarian tumors | ||
|---|---|---|
| Benign | Borderline | Malignant |

WHO Classification of Ovarian Epithelial Tumors
- WHO classifies epithelial ovarian tumors on the basis of histology as follows:[2][3][4][5][6]
- Serous tumors:
- Benign (cystadenoma)
- Borderline tumors (serous borderline tumor)
- Malignant (serous adenocarcinoma)
- Mucinous tumors:
- Benign (cystadenoma)
- Borderline tumors (mucinous borderline tumor)
- Malignant (mucinous adenocarcinoma)
- Endometrioid tumors:
- Benign (cystadenoma)
- Borderline tumors (endometrioid borderline tumor)
- Malignant (endometrioid adenocarcinoma)
- Clear cell tumors:
- Benign
- Borderline tumors
- Malignant (clear cell adenocarcinoma)
- Transitional cell tumors:
- Brenner tumor
- Brenner tumor of borderline malignancy
- Malignant Brenner tumor
- Transitional cell carcinoma (non-Brenner type)
- Epithelial-stromal:
- Adenosarcoma
- Carcinosarcoma (formerly mixed Müllerian tumors)
- Serous tumors:

Epithelial Ovarian Cancer Classification Based on Clinicopathologic and Molecular Evidence
- Recent advances in histopathology and a better understanding of clinicopathologic characteristics have led to a classification system that correlates histology and clinical characteristics.
- This classification subdivides malignant ovarian tumors in two types.
- Type I tumors generally arise from endometriosis or fallopian tubal related serous epithelium. They exhibit less aggressive clinical course and a different genetic profile relative to Type II.[1][3]
- Type II tumors generally arise from fallopian tubal epithelium. They exhibit more aggressive clinical course and a different genetic profile relative to Type I.[1][3]
