Mesothelioma - benign-fibrous

  • 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
    • 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:

  • Exams 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:

  • Treatment
    • Treatment is usually to remove the tumor.

  • Outlook (Prognosis)
    • The outcome is expected to be good with prompt treatment. The condition may return in about 1 out of 10 cases. It may return up to 10 years later.

  • Possible Complications
    • Fluid escaping into the membranes around the lungs (pleural effusion) is a complication.

  • When to Contact a Medical Professional
    • Call for an appointment with your health care provider if you notice symptoms of mesothelioma.
