Non-cancerous tumours of the mesothelium
A non-cancerous (benign) tumour is a growth that doesn’t spread (metastasize) to other parts of the body. Benign tumours of the mesothelium (also called mesothelial tumours) are not usually life-threatening.
Fibrous tumour of the pleura
A fibrous tumour of the pleura may also be called a solitary fibrous tumour. This type of tumour usually starts in the inner layer of the pleura that covers each lung (called the visceral pleura). It may also start in the outer layer of the pleura that lines the chest wall (called the parietal pleura).
Fibrous tumours of the pleura can cause many of the same symptoms as mesothelioma, such as shortness of breath. They are usually removed with surgery, but sometimes they can grow back.
Rare non-cancerous tumours of the mesothelium
Other types of mesothelial tumours are very rare. These include:
- adenomatoid tumours
- well-differentiated papillary mesothelial tumours
- peritoneal inclusion cysts
These tumours are usually removed with surgery. But sometimes non-cancerous tumours of the mesothelium don’t need to be treated.
