Malignant Peripheral Nerve Sheath Tumor

Surg Oncol Clin N Am. 2016 Oct;25(4):789-802. doi: 10.1016/j.soc.2016.05.009.

Abstract

Malignant peripheral nerve sheath tumor (MPNST) is the sixth most common type of soft tissue sarcoma. Most MPNSTs arise in association with a peripheral nerve or preexisting neurofibroma. Neurofibromatosis type is the most important risk factor for MPNST. Tumor size and fludeoxyglucose F 18 avidity are among the most helpful parameters to distinguish MPNST from a benign peripheral nerve sheath tumor. The histopathologic diagnosis is predominantly a diagnosis of light microscopy. Immunohistochemical stains are most helpful to distinguish high-grade MPNST from its histologic mimics. Current surgical management of high-grade MPNST is similar to that of other high-grade soft tissue sarcomas.

Keywords: Atypical neurofibroma; Malignant peripheral nerve sheath tumor; NF1; Neurofibroma; Neurofibromatosis.
