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 the pancreatic serous cystadenoma.
Serous cystadenofibroma and adenofibroma of the ovary can be considered variants, and are also dealt with in this article.

- 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.

- Usually unilocular.
