^ http://www.ebi.ac.uk/efo/EFO_0000693


A neoplasm that arises from SCHWANN CELLS of the cranial, peripheral, and autonomic nerves. Clinically, these tumors may present as a cranial neuropathy, abdominal or soft tissue mass, intracranial lesion, or with spinal cord compression. Histologically, these tumors are encapsulated, highly vascular, and composed of a homogenous pattern of biphasic fusiform-shaped cells that may have a palisaded appearance (MeSH).

A benign, usually encapsulated slow growing tumor of the peripheral nervous system composed of well differentiated Schwann cells. It recurs infrequently and only rare cases associated with malignant transformation have been reported.

A tumor of the peripheral nervous system composed of neoplastic Schwann cells. The vast majority of schwannomas follow a benign clinical course. Only rare cases associated with a malignant clinical course have been reported.
