Solitary fibrous tumor

Mesothelioma - benign; Mesothelioma - fibrous; Pleural fibroma

 

Solitary fibrous tumor (SFT) is a noncancerous tumor of the lining of the lung and chest cavity, an area called the pleura. SFT used to be called localized fibrous mesothelioma.

Causes

 

The exact cause of SFT remains unknown. This type of tumor affects men and women equally.

 

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
  • Clubbed appearance of the fingers

 

Exams and Tests

 

SFT is usually found by accident when a  chest x-ray is done for other reasons. If the health care provider suspects SFT, tests will be ordered. These may include:

  • CT scan of the chest
  • Open lung biopsy

The diagnosis of SFT is difficult compared with the cancerous type of this disease, called malignant mesothelioma, which is caused by exposure to asbestos. SFT is not caused by asbestos exposure.

 

Treatment

 

Treatment is usually to remove the tumor.

 

Outlook (Prognosis)

 

The outcome is expected to be good with prompt treatment. In rare cases, the tumor may return.

 

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 provider if you notice symptoms of SFT.
