Multiple melanocytoma of the thoracic spine: a case report and literature review.

Abstract

Primary melanocytic neoplasms of the central nervous system (CNS) are rare tumors, and multiple localized melanocytoma are even rarer. This study aimed to report an unusual case of multiple melanocytoma of the thoracic spine and discuss the diagnosis and treatment of primary CNS melanocytoma. This study used a clinical case report and review of the literature. Chart review and analysis of the relevant literature were carried out. A 60-year-old man presented at our neurosurgery department with progressive truncal numbness spanning 3 months. Magnetic resonance imaging of the thoracic spine revealed two intradural extramedullary masses at T1 and T3-T4, respectively. Gross total resection of the lesions was performed. Postoperative positron emission tomography-computed tomography and magnetic resonance imaging revealed no residual tumor or recurrence. We report a case of multiple primary spinal cord melanocytoma at the T1 and T3-T4 levels.
