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.
Tumor
A tumor is an abnormal growth of body tissue. Tumors can be cancerous (malignant) or noncancerous (benign).
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:

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.
Pleural effusion
A pleural effusion is a buildup of fluid between the layers of tissue that line the lungs and chest cavity.
