A nerve sheath tumor is a type of tumor of the nervous system (nervous system neoplasm) which is made up primarily of the myelin surrounding nerves. Nerve sheath tumors can be benign or malignant, and may affect both the peripheral and central nervous systems. There are three main types of nerve sheath tumors: schwannomas, neurofibromas, and malignant peripheral nerve sheath tumors.
