Benign tumours of the mesothelium
A benign tumour of the mesothelium is a non-cancerous growth that does not spread (metastasize) to other parts of the body and is not usually life-threatening. They can occur in either men or women and are very rare. These tumours are usually removed by surgery.
Fibrous tumour of the pleura
A single fibrous tumour of the pleura is a benign tumour that forms in the visceral or parietal pleura. This type of tumour can occur in both men and women. A benign fibrous tumour of the pleura can cause symptoms similar to malignant mesothelioma, such as shortness of breath. It may also change into a malignant tumour. A benign fibrous tumour of the pleura can recur after surgery is done to remove it.
Multicystic mesothelioma forms several benign cysts in the peritoneum. This type of mesothelioma most often occurs in women. It may also be called benign cystic mesothelioma.
Adenomatoid mesothelioma is a benign tumour that usually develops in the mesothelium of the male and female reproductive organs (genital system).
- In men, this benign tumour often starts in the epididymis (the tightly coiled tube within the testicle that stores and carries sperm cells).
- In women, adenomatoid mesothelioma starts in the Fallopian tubes (the tubes that carry eggs from the ovaries to the uterus).
