Extramedullary malignant melanotic schwannoma of the spine: Case report and an up to date systematic review of the literature.

ABSTRACT:

Background

Melanotic schwannoma is a rare variant of schwannoma. Extramedullary melanotic schwannoma originates in the vicinity of nerve roots mimicking other intervertebral disc disorders.
