The Brenner tumour, abbreviated BT, is an ovarian tumour in the epithelial group of ovarian tumours.
General
- Considered to be rare.[1]
- 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.[2]
Epidemiology
- Mostly benign clinical course.
- Thought to arise from Walthard cell rest.
- Frequently an incidental finding, i.e. oophorectomy was done for another reason.
- May be malignant.
Gross
Features:[3]
- Classically solid, well-circumscribed, light yellow.
- May be cystic.
Note:
- Borderline tumours classically solid and cystic with papillary projections into the cystic component.[3]
Microscopic
Features:
- Nests of transitional epithelium with cells that have:[4]
- A "coffee bean nucleus".
- Elliptical shape (nucleus).
- Nuclear grooves.[5]
- 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.
