Intracranial and spinal melanotic schwannoma in the same patient.

Melanotic schwannoma is a nerve sheath tumor composed of melanin - producing cells with ultrastructural features of Schwann cells, which is very rare. These tumors can appear intracranially and less common in the spinal canal. The prognosis is usually good although cases with metastases and death are described in the literature. We present the unusual and rare case of a young man with a spinal melanotic schwannoma at L5/S1 who presented 30 months later with an intracranial melanotic schwannoma.
