Benign mucinous cystadenoma of ovary is a non cancerous tumor of ovary. It usually occurs in women during early forties or post menopausal period. Since this tumor is not cancerous, it does not spread to other areas. However, the tumor can grow extensively in size imitating a cancerous growth.
Benign mucinous cystadenoma of ovary is an epithelial cell tumor. These tumors grow slowly. In majority of cases the growth occurs only in one ovary with a single mass. Sometime the tumor can be present in multiple within the ovary. The tumor is classified as mucinous of the type of its epithelial cell.Epithelial cell can be serous, mucinous, or mixed variety.
The symptoms of benign mucinous cystadenoma of ovary are pain in abdomen, enlarged abdomen size, vaginal bleeding. A large size tumor can cause rupture, hemorrhage and torsion of the ovary. The exact cause of this ovarian pathology is not known, but obese women have greater propensity for its development. Treatment is complete surgical removal of the mass. Prognosis of this tumor is good.
Causes Of Ovarian Mucinous Cystadenoma
The etiology of benign mucinous cystadenoma of ovary is not fully understood. These tumors develop spontaneously. Certain changes in the genetic characteristic are seen in some cases of such tumor by researchers; however, these types of mutations are seen rarely.
It can occur in any women between 20 and 80 years of age. But many cases are reported during in the middle aged women. It rarely occurs in adolescent and teenage girls. There is no specific risk factor detected but obese women and women taking hormone replacement therapy are found to be at greater risk.
Symptoms Of Mucinous Cystadenoma In Ovary
Many cases of benign mucinous cystadenoma of ovary remain asymptomatic. The growth of tumor is slow. Normally only one ovary is affected. Sometime the disease is bilateral. It is a small sized tumor about 5 cm in diameter. But the tumor can grow from 10 to 15 cm in some women.
However, symptoms when develop are as follows:
- Pain in the lower abdomen.
- The abdomen appears swollen due to the enlarged size of tumor.
- Later in some cases there is collection of abdominal fluid which enlarges the size of abdomen.
- Due to collection of fluid in the abdomen (ascites), there is gradual increase in the abdominal girth.
- Large sized tumor can compress the colon. This may lead to constipation and difficulty in bowel movement.
- Eating small amount of food results in fullness of stomach.
- Nausea and vomiting
- Decreased appetite
- Tiredness and fatigue
- Menstrual abnormality
Mucinous Cystadenoma In Ovary Diagnosis
For diagnosis of the ovary tumor a complete medical history, physical and pelvic examination as well as blood and radiological tests are primary.
Following tests are useful in the case of ovarian tumor:
- Complete blood count
- Inhibin hormonal test
- Alpha feto protein
- Estrogen and testosterone test.
- Human chorionic gonadotrophin test.
- CT SCAN and MRI of pelvis and abdomen.
- Ultrasound scan
Biopsy of the tumor is performed with the help of exploratory laprotomy. The tissue collected is sent to the laboratory for examination. The examination biopsy report of the pathologist is considered as the final conclusion of the disease.
Treatment Of Mucinous Cystadenoma Of Ovary
Benign mucinous cystadenoma of ovary treatment depends on the size of tumor. If the tumor is extremely small, usually no treatment is necessary. The tumor is benign. The doctor will monitor the patient periodically for any further deterioration. He may advice certain tests such as inhibin test and ultrasound during the follow up visits.
In case if the tumor starts growing, surgical excision is necessary to reduce the symptoms and complications such as hemorrhage and torsion of the ovary. After the surgery, patient is advised to do minimum physical work until complete healing takes place.
