The Brenner tumour, abbreviated BT, is an ovarian tumour in the epithelial group of ovarian tumours.
General
- Considered to be rare[1] - 1-2% of ovarian neoplasms.[2]
- Traditionally, BT has been grouped within the transistional cell tumours category in the surface epithelial group of ovarian tumours.
- Recently, transistional cell carcinoma of the ovary has been related to serous carcinoma; TCC of the ovary is probably distinct from the malignant Brenner tumour.[3]
- May arise from the fallopian tube.[4]
- Can be seen in the testis.[5]
Epidemiology
- Mostly benign clinical course - 99% of Brenner tumours benign.[6]
- Thought to arise from Walthard cell rest.
- Frequently an incidental finding, i.e. oophorectomy was done for another reason.
- May be malignant - rarely (~1% of Brenner tumours[7]).
Gross
Features:[8]
- Classically solid, well-circumscribed, light yellow.
- May be cystic.
Note:
- Borderline tumours classically solid and cystic with papillary projections into the cystic component.[8]
Microscopic
Features:
- Nests of transitional epithelium with cells that have:[9]
- A "coffee bean nucleus".
- Elliptical shape (nucleus).
- Nuclear grooves.
- Distinct nucleoli.
- Moderate-to-abundant gray/pale cytoplasm.
- A "coffee bean nucleus".
- Dense fibrous stroma around nests.
Notes:
- Main DDx of Coffee bean nucleus = granulosa cell tumour.
- Stromal component may be predominant.
DDx:[6]
- Benign:
- Endometrioid adenofibroma.
- Ovarian fibroma.
- Borderline:
- Benign Brenner tumour.
- Malignant Brenner tumour.
- Metastatic papillary urothelial carcinoma.
- Malignant:
- Undifferentiated carcinoma - no Brenner tumour component.
- Granulosa cell tumour.
- Serous carcinoma.
- Metastatic urothelial carcinoma.
- Walthard cell rest - typically one nest of cells, lacks the surrounding fibromatous stroma.
