Abstract (Original Language):
Melanocytoma is a well differentiated neoplasm arising from leptomeningeal melanocytes. It was first described by Limas and Tio in 1972 (1). Lep-tomeningeal melanocytes are derived from the neural crest and they are found at highest den-sity underneath the medulla and along the cervi-cal spinal cord (2,3). Most tumors occur in the posterior fossa and the spinal cord (4). The prog-nosis of melanocytoma patients is usually fa-vorable, however local recurrence is not un-common. Rarely progression to malignant mela-noma, leptomeningeal spread and even distant metastases have been reported (4-6).
