Serous carcinoma of the ovary, also ovarian serous carcinoma, is relatively common malignant ovarian tumour.
General
- Most common malignant ovarian tumour in the eldery.
- Poor prognosis.
- Thought to arise from serous tubal intraepithelial carcinoma (STIC).[1]
Microscopic
Features:
- Marked nuclear pleomorphism:
- Variation in size - usually marked.
- Variation in staining.
- Variation in shape.
- Prominent nucleolus - key feature.
- Eccentric nucleus.
- Architecture:
- Solid.
- Papillary - classic.
- Glandular - uncommon.
- +/-Psammoma bodies - uncommon.
- +/-Necrosis - often extensive.
DDx:
- Clear cell carcinoma of the ovary - less nuclear size variation.
- Endometrioid carcinoma of the ovary - usu. lower grade.
- Primary peritoneal serous carcinoma - bulk of tumour in peritoneum, small ovarian tumour.
- Other non-ovarian serous carcinomas - see serous carcinoma.
- Ovarian serous borderline tumour - mild to moderate nuclear atypia, no invasion, few mitoses.
Grading
Serous carcinoma is subdivided into:[2][3]
- Low-grade (Type I).
- High-grade (Type II).
Note:
- Tumours very rarely transform from low-grade to high-grade.[2]
Images
Serous carcinoma - cytology. (WC)
IHC
Others:
- HNF-1beta -ve.[6][7]
- Usually +ve in clear cell carcinoma of the ovary.
