Surface Epithelial Ovarian Tumors
Surface Epithelial Ovarian Tumors
Most common type of ovarian tumor, accounting for 70% of cases. These tumors arise from the coelomic epithelium, which is the same embryonic tissue that forms the fallopian tube lining and the endometrium.
Serous Tumor
Serous Tumor
A type of surface epithelial tumor characterized by watery fluid. Can be benign, borderline, or malignant.
Mucinous Tumor
Mucinous Tumor
A type of surface epithelial tumor characterized by thick mucous fluid. Can be benign, borderline, or malignant.

Study Notes
Ovarian Tumors: Basic Principles
- Ovaries consist of three cell types: surface epithelium, germ cells, and sex cord-stromal cells
- Ovarian tumors can originate from any of these cell types or through metastasis
- Surface epithelial tumors are the most common type (70%)
Surface Epithelial Tumors
- These tumors arise from the coelomic epithelium lining the ovary
- This epithelium also develops the lining of the fallopian tubes, endometrium, and endocervix
- Common subtypes are serous and mucinous, typically cystic
- Serous tumors contain watery fluid
- Mucinous tumors contain mucus-like fluid
- These tumors can be benign, borderline, or malignant
- Benign (cystadenomas): characterized by a single cyst with a simple lining; typically affect premenopausal women (aged 30-40)
- Malignant (cystadenocarcinomas): involve complex cysts with thick, irregular lining; common in postmenopausal women (aged 60-70)
- Borderline tumors have characteristics between benign and malignant; have a better prognosis than malignant tumors but still have metastatic potential
- BRCA1 mutation carriers have a higher risk of serous ovarian and fallopian tube carcinoma
- Prophylactic salpingo-oophorectomy (removal of fallopian tubes and ovaries) and prophylactic mastectomy (breast removal) may be considered for these carriers
- Other less common subtypes include endometrioid and Brenner tumors
- Endometrioid tumors are typically malignant and resemble endometrial tissue
- Brenner tumors are usually benign and resemble bladder tissue
Additional Information
- Prognosis for surface epithelial carcinoma is generally poor, as it is one of the worst prognoses in female genital tract cancers
- Epithelial carcinomas, in general, tend to spread locally, especially to the peritoneum
- CA-125 is a serum marker useful to monitor treatment response and screen for recurrence of ovarian cancer
