Intradural extramidullary dorsal melanocytoma in the adult: case report and review of the literature
Intradural Extramedullary Spinal Melanocytoma (IESM) is an extremely uncommon tumour arising from the spinal leptomeninges; both from a gross pathology and microscopic point of view it can mimick its malignant counterpart, the Melanoma. Such tumours are usually solitary, with a lower proliferating rate and without obvious SC invasion. Their common differential diagnoses include Spinal Schwannoma and Spinal Meningiomas since they share a significant amount of radiological similarities.
