Mucinous tumour Wikipedia

Mucinous tumours are part of the surface epithelial-stromal tumour group of ovarian neoplasms, and account for 12-15% of all ovarian tumours.
Approximately 75% are benign, 10% are borderline and 15% are malignant.
Rarely, the tumour is seen bilaterally, though this is uncommon.

Benign mucinous tumours are typically multilocular (have several lobes), and the cysts have a smooth lining of epithelium that resembles cervix|endocervical epithelial cells with small numbers of gastrointestinal-type epithelial cells.
Borderline and malignant mucinous tumours often have papillae and solid areas.
There may also be hemorrhage and necrosis.
It is well-documented that malignancy may be only focally present in mucinous neoplasms of the ovary, so thorough sampling is imperative.
The microscope|microscopic pathology|pathological appearances of borderline and carcinomatous mucinous tumours are quite variable and there is some uncertainty and controversy about diagnostic criteria.
