Mesothelioma (benign-fibrous)

Definition

Benign mesothelioma is a noncancerous tumor of the pleura (lining of the lung and chest cavity).

Causes, incidence, and risk factors

Nonmalignant mesothelioma is usually a localized tumor that affects men more frequently than women. The tumor may grow to a large size and compress the lung, causing the symptoms of shortness of breath.

Symptoms

• Chronic cough
• Shortness of breath
• Chest pain

Approximately half of mesothelioma patients are asymptomatic (show no symptoms of disease).

Signs and tests

During a physical examination, the health care provider may notice a clubbed appearance of the fingers.

Tests that may show mesothelioma include the following:

• Chest x-ray
• CT scan of the chest
• Open lung biopsy

Treatment

Surgery is usually necessary for a solitary tumor.

Expectations (prognosis)

The outcome is expected to be good with prompt treatment.

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.
