Clinically, patients may present with an abdominal mass. Symptoms depend on the patient's age. The most important indicator of prognosis is tumor stage. Age over forty years at the time of the initial diagnosis, large tumor size, bilaterality, cellular atypia, and increased mitotic activity are factors indicating a potentially aggressive clinical course and relative poor prognosis. |

A low grade ovarian epithelial tumor composed of an admixture of two or more of the five major cell types: serous, mucinous, endometrioid, clear cell, and Brenner/transitional. The second or second and third cell types must comprise alone or together at least 10% of the tumor epithelium. The majority of patients present with stage I tumor and a minority present with bilateral disease. Morphologically, it shows papillae with detached cell clusters. Microinvasion may be seen rarely.

A neoplasm of low malignant potential arising from the ovary. It is characterized by the proliferation of neoplastic epithelial cells that resemble endocervical epithelial cells. There is no evidence of stromal invasion. |
| Mucinous borderline tumor, intestinal type (WHO code: 3472/1) |
Borderline Ovarian Mucinous Tumor, Intestinal Type |
C40037 |
NCI Thesaurus |
A neoplasm of low malignant potential arising from the ovary. It is characterized by the proliferation of neoplastic mucinous epithelial cells that resemble intestinal epithelial cells. There is no evidence of stromal invasion. |
| Mucinous carcinoma (WHO code: 8480/3) |
Ovarian Mucinous Adenocarcinoma |
C5243 |
NCI Thesaurus |
An invasive adenocarcinoma that arises from the ovary and is characterized by the presence of malignant epithelial cells that contain intracytoplasmic mucin. There is cellular atypia, increased layering of cells, complexity of glands, and papillary formations. |
| Mucinous cystadenocarcinoma (WHO code: 8470/3) |
Ovarian Mucinous Cystadenocarcinoma |
C4026 |
NCI Thesaurus |
An invasive cystic adenocarcinoma arising from the ovary. It is characterized by the presence of malignant glandular epithelial cells which contain intracytoplasmic mucin. The malignant cells invade the ovarian stroma and the cystic spaces contain mucoid material. In a minority of cases both ovaries are involved by the tumor. The prognosis for stage I tumors is excellent. Patients with metastases usually have a poor prognosis. |
