[Intradural and cervical primary malignant melanoma. Case report and review of the literature].

Primary malignant melanoma of the central nervous system is an uncommon localization, first reported by Hirsberg in 1906. Since then, to our knowledge, only 39 cases have been reported in the literature. We present a case of primary intradural extra-medullary melanoma which developed in a 51-Year-old man who complained of pain in the lower cervical spine, difficulties in micturition and sexual impotence. The diagnosis was suspected at the MRI which showed a lesion with a paramagnetic signal and was confirmed by the histological examination. The resection was complete and the course has been satisfactory after 19 months follow-up.
