Meningeal melanocytoma: case report and review of the literature

We report a case of meningeal melanocytoma in the thoracic spinal cord of a 44-year-old woman and review previously documented cases. Our patient experienced numbness and tingling in her left leg for 8 years, and low back pains with intermittent claudication for the previous 2 months. A histologically benign 20-mm tumour was totally resected. Radiation therapy was not given. The tumour showed the histological, immunohistochemical and ultrastructural features of a meningeal melanocytoma. The patient is alive without recurrence 4.5 years after surgery.
