Abstract

Malignant peripheral nerve sheath tumors (MPNSTs) are tumors that arise from cellular components of a normal nerve, i.e., Schwann cells and perineurial cells. They are relatively uncommon and very aggressive soft-tissue tumors seen in two settings, sporadic and associated with neurofibromatosis (NF) type 1. Despite the two clinical scenarios, the biological background, loss of NF1 expression by deletion or mutation, is believed to be similar. Older, abandoned terms for MPNST include neurofibrosarcoma, malignant schwannoma, and neurogenic sarcoma.
