It is unrelated to mucinous cystadenoma of the appendix.

- Cysts lined by a simple mucinous epithelium.
- No cytologic atypia.
Note:
- A borderline component may be present but must be <10% of the tumour.[4]
- Lesions with <10% borderline component are known as mucinous cystadenoma of the ovary with focal proliferation or mucinous cystadenoma of the ovary with focal atypia.
