'Schwannomas are unusual benign tumors which arise from the surface of neural
elements of the body or within the brain. They do not as a rule metastasize but
may cause sometimes severe local problems on the nerves, blood vessels and
adjacent bone. The tumors arise from the Sheath of Schwann, a structure on the
surface of a nerve. The lesions may expand and cause considerable damage to
adjacent tissues. They do not arise within bone since there are no Sheaths of
Schwann within the osseous tissue but may cause local damage to the bony cortex
and sometimes fractures. Rarely the lesions may metastasize and cause patients'
death. The treatment is usually local resection, and most often is successful
although may cause damage to the adjacent nerve.
