A malignant peripheral nerve sheath tumor is rare, but is one of the most common frequent soft tissue sarcoma in the pediatric population. About half of these cases also happen to occur along with neurofibromatosis type 1 (NF-1), which is a genetic mutation on the 17th chromosome which causes tumors along the nervous system.
New and more precisely defined entities include malignant melanotic nerve sheath tumor (formerly known as melanotic schwannoma) and hybrid nerve sheath tumors. [4] [5] The majority of peripheral nerve tumors are benign tumors of the nerve sheath (usually schwannomas); on rare occasions, they are metastatic tumors or originate from the nerve cells.
Each nerve sheath tumor type has a few different associated features on MRI imaging. Neurofibromas and malignant peripheral nerve sheath tumors can be difficult to distinguish from each other and may require additional testing, including PET scans (18 FDG-PET). [1] Image-guided needle biopsies may be performed if there is concern for malignancy ...

A sarcoma is a malignant tumor, a type of cancer that arises from cells of mesenchymal (connective tissue) origin. [ 1 ] [ 2 ] Connective tissue is a broad term that includes bone , cartilage , muscle , fat , vascular , or other structural tissues, and sarcomas can arise in any of these types of tissues.
Malignant melanotic nerve sheath tumor (previously known as melanotic schwannoma) is a rare aggressive peripheral nerve sheath tumor that typically develops in conjunction with spinal or visceral autonomic nerves, consisting uniformly of Schwann cells displaying melanocytic differentiation.
A soft-tissue sarcoma (STS) is a malignant tumor, a type of cancer, that develops in soft tissue. [1] A soft-tissue sarcoma is often a painless mass that grows slowly over months or years. They may be superficial or deep-seated. Any such unexplained mass must be diagnosed by biopsy. [2]
