A malignant peripheral nerve sheath tumor (MPNST) is an extremely rare soft tissue tumor in the general population. On the other hand, there is a higher incidence of MPNST in patients with neurofibromatosis type I (von Recklinghausen's disease). The common sites are the extremities, trunk, head and neck.

Malignant peripheral nerve sheath tumors of the scalp are rare lesions of the nervous system. Only 16 cases have been reported to date. In this report, we present a case of a malignant peripheral nerve sheath tumor (MPNST) of the scalp and retrospectively analyze the clinical features, imaging findings, pathological features, and prognoses of these tumors.
Malignant peripheral nerve sheath tumors (MPNSTs) are very rare sarcomas derived from various cells in the peripheral nerve sheath. Malignant peripheral nerve sheath tumors have a known association with neurofibromatosis type 1. Diagnosis of MPNSTs is difficult in patients with chronic pain, when MPNST occurs at an overlapping area of chronic pain. Therefore, the diagnosis can be missed unless ...
Malignant peripheral nerve sheath tumor (MPNST) is an aggressive neoplasm of neural origin. It is a rare neoplasm of childhood, accounting for less than 5% of all cases.

Here we present the case of a 36-year-old man who was found to have a symptomatic malignant neural sheath tumor growing from the C2 nerve root following a period of progressively worsening headaches. The patient was successfully treated with surgical resection resulting in resolution of cranial nerve deficits. Though uncommon, malignant peripheral nerve sheath tumor must be considered in the di...
