What is a Brenner tumor of the ovaries?
Brenner tumors are an uncommon surface epithelial tumor of the ovary. It was originally known as a transitional cell tumor due to its histological similarity to the urothelium. Brenner tumors account for ~3% of ovarian epithelial neoplasms. They can very rarely occur in other locations, including the testis.
Is Brenner tumor malignant?
The vast majority of Brenner tumors are benign, often incidental findings; however, malignant Brenner tumors (MBT) do occasionally occur.
How do you treat an ovary tumor?
Treatment of the ovarian mass or tumor depends on the most likely diagnosis and patient’s symptoms. Most ovarian cysts do not cause significant symptoms, resolve spontaneously, and therefore require no surgical intervention. Endometriomas require surgical removal if they cause pain.
What type of tumor is a Brenner tumor?
Brenner tumors are a subtype of the transitional cell neoplasms of the ovary and account for about 2% of ovarian neoplasms. Most are benign, and less than 10% of cases occur bilaterally. Most Brenner tumors are solid, but some contain small or large cystic areas that may show mucinous differentiation.
What causes Brenner tumors?
The cause of Brenner tumors is unknown. They are usually found by accident during surgery for another reason or during a routine doctor’s examination. The diagnosis is made by microscopic examination of a piece of tumor obtained by a surgical biopsy. Treatment usually consists of surgery to remove the tumor.
Is Brenner tumor bilateral?
Usually, benign Brenner tumors are unilateral and malignant Brenner tumors are bilateral(21).
What percentage of Brenner tumor is malignant?
Objectives: Malignant Brenner tumors (MBT) of the ovary are rare diseases, representing 1% of all ovarian cancers and 3-5% of Brenner tumors. They carry a poor prognosis. They generally affect women during the perimenopausal and postmenopausal periods.
Is Thecoma benign?
A thecoma is a benign tumor that consists entirely of stroma (theca) cells. It predominantly occurs in women in their perimenopausal and menopausal years. These tumors can be associated with estrogen production but not as often as granulosa cell tumors.
How are benign ovarian tumors treated?
Benign tumours are usually treated by surgery to remove the part of the ovary that contains the tumour or the entire ovary. Benign epithelial tumours are the most common type of benign ovarian tumour. They start from the cells that cover the outer surface of the ovary.
What happens when there is tumor in ovary?
Ovarian cancer is a type of cancer that begins in the ovaries. The ovaries — each about the size of an almond — produce eggs (ova) as well as the hormones estrogen and progesterone. Ovarian cancer is a growth of cells that forms in the ovaries. The cells multiply quickly and can invade and destroy healthy body tissue.
How is MEIG syndrome diagnosed?
Diagnosis of Meigs syndrome Chest radiography confirms pleural effusion. Abdominal and pelvic ultrasonography confirms the ovarian mass and ascites. Computed tomography scanning of the abdomen and pelvis confirms ascites and the presence of an ovarian, uterine, fallopian tube, or broad ligament mass.
What does Androblastoma mean?
Listen to pronunciation. (AN-droh-blas-TOH-muh) A rare type of ovarian tumor in which the tumor cells secrete a male sex hormone. This may cause virilization (the appearance of male physical characteristics in females).
What is a Brenner tumor?
Brenner tumors are an uncommon surface epithelial tumor of the ovary. It was originally known as a transitional cell tumor due to its histological similarity to the urothelium. Brenner tumors account for ~3% of ovarian epithelial neoplasms. They can very rarely occur in other locations, including the testis.
Are tumors on the ovary usually cancerous?
While these symptoms are usually nothing to worry about, they could be a sign of ovarian cancer if they are persistent and frequent. If you experience any combination of these symptoms more than 12 times a month, Target Ovarian Cancer recommends visiting your GP.
What are the symptoms of a benign ovarian tumor?
Symptoms and Signs of Benign Ovarian Masses. Most functional cysts and benign tumors are asymptomatic. Sometimes they cause menstrual abnormalities. Hemorrhagic corpus luteum cysts may cause pain or signs of peritonitis, particularly when they rupture. Occasionally, severe abdominal pain results from adnexal torsion.
How big are ovarian cancer tumors?
The defi nition of large ovarian cysts varies from those measuring more than 10 cm in diameter in preoperative scans to those reaching above the umbilicus.3 On the basis of cell of origin, ovarian neoplasms are divided into epithelial, stromal and germ cell neoplasms. Ovarian epithelial tumors constitute about half of all the ovarian tumors.
