[Melanocytic schwannoma. A case report and review of the literature].
METHODS
We report a new unusual case of a patient without known familiar history of melanocytic schwannoma or Carney complex with multiple melanocytic schwannoma in the spinal canal. Histologically, the tumor was composed of irregular interlacing spindle-shaped cells with pigments. The diagnosis is made by immunohistochemical techniques and electron microscopy findings.


CONCLUSIONS
We review the literature, and the different theories on the origin of these tumors are discussed.
