[Primary amelanotic meningeal melanomatosis]

Primary melanocytic lesions of the central nervous system are rare. The spread of melanoma cells primarily into the meningeal layers is referred to as meningeal melanomatosis. A few case reports about either intracranial or intraspinal primary meningeal melanoma were published in the past. The amelanotic variation of primary melanoma in the central nervous system is a very rare event and so far no cases of primary amelanotic meningeal melanomatosis have been described in the current literature. We present a case with combined multiple intracranial and intraspinal primary malignant amelanotic melanomas.
