Definition

Benign mesothelioma is a noncancerous tumor of the lining of the lung and chest cavity, an area called the pleura.

It is also called solitary fibrous tumor of the pleura.

See also: Malignant mesothelioma

Alternative Names

Mesothelioma – benign; Mesothelioma – fibrous; Pleural fibroma; Solitary fibrous tumor of the pleura

Causes, incidence, and risk factors

This type of tumor more often affects men than women.

Symptoms

About half of the people with this type of tumor do not show any symptoms.

If the tumor grows to a large size and pushes on the lung, it can lead to symptoms, such as:

  • Chest pain
  • Chronic cough
  • Shortness of breath

Signs and tests

During a physical examination, the health care provider may notice a clubbed appearance of the fingers. The tumor is usually found by accident when a chest x-ray is done for other reasons.

Other tests that may show benign mesothelioma include:

  • CT scan of the chest
  • Open lung biopsy

Treatment

Treatment is usually needed to remove the tumor.

Expectations (prognosis)

The outcome is expected to be good with prompt treatment. The condition may return in about 1 out of 10 cases. It may reoccur as long as 10 years later.

Complications

Pleural effusion (fluid escaping into the membranes around the lungs) is a complication.

Calling your health care provider

Call for an appointment with your health care provider if you notice symptoms of mesothelioma.
