Serous cystadenoma of the ovary is a common benign finding in the ovary.
It is also known as ovarian serous cystadenoma. It is unrelated the pancreatic serous cystadenoma.
Serous cystadenofibroma and adenofibroma of the ovary can be considered variants, and are also dealt with in this article.
General
- Benign.
- Very common.
- Not related to the serous cystadenoma of the pancreas.
- Thought to arise from a cortical inclusion cyst that has undergone Muellerian metaplasia[1][2] - see mesothelial inclusion cyst.
Gross
Cystadenoma:
- Usually unilocular.
Cystadenofibroma and adenofibroma:[3]
- Solid or solid and cystic.
Note:
- Cystic lesions must be >=1 cm in size, smaller lesions are surface epithelial inclusion cysts.[4]
Image
Microscopic
Features:[5]
- Simple epithelium - key feature - usually with cilia.
- Cell morphology: columnar, cuboidal or flatted.
- Absent or minimal nuclear atypia.
- +/-Rare tufting.
- +/-Non-branching papillae.
- +/-Rare mitoses.
Note:
- May have calcifications - uncommon.[6]
DDx:
- Cortical inclusion cyst - <1 cm in size, see mesothelial inclusion cyst.
- Ovarian serous borderline tumour - branching papillae, tufting, mitoses, nuclear atypia.
Note - the following may be lumped with this entity:
- Serous cystadenofibroma.
- Adenofibroma.

FALLOPIAN TUBE AND OVARY, RIGHT, SALPINGO-OOPHORECTOMY: - BENIGN SEROUS CYSTADENOMA AND SEROUS CYSTADENOFIBROMA WITH FOCAL ATYPIA, SEE COMMENT. - FALLOPIAN TUBE WITHIN NORMAL LIMITS. - NEGATIVE FOR MALIGNANCY. COMMENT: A small focus of the sampled tissue has a complex architecture, compatible with a borderline tumour; however, it represents less than 10% of the lesion. Thus, the lesion is best classified as benign with focal atypia.
Micro
The sections show fibrous tissue consistent with a cyst wall lined by a simple columnar to flat epithelium, focally with cilia.
Cautery is present imparting a pseudostratified appearance focally. No definite papillae or definite tufting is apparent. No significant nuclear atypia is seen. Mitotic activity is not apparent.
