What is a mucinous cystadenoma of the ovary?

Ovarian mucinous cystadenoma is a benign tumour that arises from the surface epithelium of the ovary. It is a multilocular cyst with smooth outer and inner surfaces. It tends to be huge in size. Of all ovarian tumours, mucinous tumours comprise 15% [1,2].

Can mucinous cystadenoma become cancerous?

Mucinous tumors are usually benign; only approximately 10% are borderline malignant, and another 10% show explicit malignancy. Mucinous cystadenocarcinoma is a less frequent finding than serous cystadenocarcinoma.

Can mucinous cystadenoma come back?

The second most common epithelial tumor of the ovary is the mucinous tumors, and it constitutes about 8–10% of all ovarian tumors. The recurrence of mucinous cystadenoma is very rare after complete excision.

What causes cystadenoma ovary?

The follicle contains fluid that protects the egg as it grows, and it bursts when the egg is released. But sometimes a follicle does not release an egg, or does not discharge its fluid and shrink after the egg is released. If this happens, the follicle can swell and become a cyst.

Is mucinous cystadenoma bilateral?

The gross pathologic findings of mucinous cystadenoma are a large unilateral cystic mass with a smooth outer surface. The mass is unilateral in approximately 95% of cases. The cyst is usually multilocular but can be unilocular.

How fast does a mucinous cystadenoma grow?

The median growth rate was 0.65 cm/year with mucinous cystadenomas growing faster at 0.83 cm/year compared to 0.51 cm/year for serous cystadenomas (median test P < . 0001).

How big can a cystadenoma grow?

Cystadenomas are one of the most common ovarian tumors; they arise from the ovarian epithelium and make up for up to 80% of benign ovarian tumors in postmenopausal women [2,4]. Cystadenomas are typically unilateral and have a mean size of 10 cm; in rare scenarios some tumors can grow to giant sizes that exceed 30 cm.
