A malignant peripheral nerve sheath tumor (MPNST) is a form of cancer of the connective tissue surrounding peripheral nerves. Given its origin and behavior it is classified as a sarcoma. About half the cases are diagnosed in people with neurofibromatosis; the lifetime risk for an MPNST in patients with neurofibromatosis type 1 is 8–13%.[2] MPNST with rhabdomyoblastomatous component are called malignant triton tumors.
The first-line treatment is surgical resection with wide margins. Chemotherapy and often radiotherapy are done as adjuvant and/or neoadjuvant treatment depending upon various risk factors.
