What is MPNST?
A malignant peripheral nerve sheath tumour (MPNST) is a type of rare cancer that develops in the connective tissue that surrounds nerves. Because of its behaviour and origin, it is classed as a sarcoma.
MPNST is also known as Schwannoma carcinoma, malignant Schwannoma, neurosarcoma and neurofibrosarcoma.
How rare is it and who does it affect?
MPNSTs occur in 0.001% of the general population which makes them quite rare. Although rare, they are one of the most common soft tissue sarcomas in children.
About half of all cases of Malignant Nerve Sheath Tumours are diagnosed in people who have Neurofibromatosis, which is a group of conditions in which tumours grow in the nervous system.
