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.
Mesothelioma - benign; Mesothelioma - fibrous; Pleural fibroma
The exact cause of SFT remains unknown. This type of tumor affects men and women equally.
About one 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:
Treatment is usually to remove the tumor.
The outcome is expected to be good with prompt treatment. In rare cases, the tumor may return.
Fluid escaping into the membranes around the lungs (pleural effusion) is a complication.
Call for an appointment with your provider if you notice symptoms of SFT.
