Summary Summary. Schwannomatosis is a rare form of neurofibromatosis that is primarily characterized by multiple schwannomas (benign tumors of the nervous system) in the absence of bilateral (affecting both sides) vestibular schwannomas.
Structure [edit]. Schwann cells are a variety of glial cell that keep peripheral nerve fibres (both myelinated and unmyelinated) alive. In myelinated axons, Schwann cells form the myelin sheath (see above). The sheath is not continuous.chwann cells are known for their roles in supporting nerve regeneration. Nerves in the PNS consist of many axons myelinated by Schwann cells. If damage occurs to a nerve, the Schwann cells will aid in digestion of its axons (phagocytosis).
