Benign Cystic Mesothelioma: Causes, Symptoms, Diagnosis, Treatment, and Prognosis

Cystic Mesothelioma Symptoms

Cystic mesothelioma is a very rare form of mesothelioma. Since 2013, roughly 153 cases have been reported worldwide, which is extremely very low.

This disease is also known as multi-cystic peritoneal mesothelioma or multi-cystic mesothelioma of the peritoneum as it starts in the lining of the abdominal cavity (peritoneum). It also starts in the pelvic peritoneum.

As of 2013, only 153 cases have been reported worldwide in medical literature.

The disease is usually benign, although in rare cases, it develops into a very aggressive, malignant cancer. However, its benign form is said to be much less dangerous compared to diffuse epithelial mesothelioma.

Even worse, it’s said to be much more severe compared to localized benign adenomatoid mesothelioma.

Incidences of Benign Cystic Mesothelioma

Because it’s an extremely rare form of mesothelioma, its incidence is very low.

Statistics show that as from 2013, only 153 diagnoses have been made and reported so far.

Of these incidences, most are reported in women who are in their child-bearing years as it mostly begins in the pelvic peritoneum and in some cases, in the peritoneum near the uterus, rectum, bladder, and omentum.

Benign multicystic peritoneal mesothelioma (BMPM) is uncommon lesion usually occurring in women of reproductive age.

The disease also affects older males where the tumor originates in the peritoneum around the bladder and rectum.

Cystic Mesothelioma Causes

The link between asbestos exposure and cystic mesothelioma has not been well established, unlike malignant mesothelioma.

Some studies suggest that because it mostly affects women, it may be related to hormonal problems which possibly trigger the growth of the tumors.

Other studies suggest that the disease develops as a result of exposure to foreign fiber and dust.

The disease is also said to occur as a result of irritation from surgery or endometriosis, which is a serious condition characterized by abnormal growth of uterine tissue in the outer region of the uterus.

Because so few cases have been reported up to now, research on this type of mesothelioma is limited, which means it’s hard to determine the actual cause.

Cystic Mesothelioma Symptoms

Because it commonly develops in the abdominal cavity, its most common symptoms include abdominal pain and a palpable mass that can be felt in the abdominal region.

Actually, most women are mostly diagnosed with this condition after experiencing these symptoms.

Other symptoms may include painful sexual intercourse, difficult or painful urination, the absence of menstruation, and unexplained weight loss.

Cystic Mesothelioma Diagnosis

Since it’s a rare condition, doctors find it difficult to diagnose, although most people are usually diagnosed while visiting the doctor for different medical complications.

The doctor may perform a standard physical exam on the patient. He/she may also order a CT scan, MRI, or ultrasound scan to determine the underlying cause of these symptoms. The scans also help physicians visualize cysts.

The doctor may also perform a biopsy and send the tissue sample to the lab for testing.

Treatments for Cystic Mesothelioma

If cystic mesothelioma is benign, it’s highly treatable and usually has a very good prognosis.

Surgery is often performed to either remove the mass. A surgical procedure may also be performed to minimize its size or drain fluids if it’s not possible to remove the whole tumor.

Surgery is the only highly effective treatment for this diagnosis. Because this type of cancer grows slowly and does not spread, its prognosis is much better than other forms of the disease.

Another potential treatment is peritoneal chemotherapy with a drug known as Cisplatin, although various trials have in the past provided different degrees of success.

Studies have however shown that there is a possibility of about half of all patients experiencing a recurrence, despite the positive response to available treatment options.

Cystic Mesothelioma Prognosis

Because it’s benign in nature, cystic mesothelioma generally has a good prognosis compared to other types of mesothelioma.

Surgery is usually a highly effective treatment option for this condition.
