摘要

Pigmented primary neoplasms of the central nervous system are uncommon. Differential diagnosis of such lesions is limited and includes pigmented meningioma, melanocytic schwannoma, and primary versus metastatic melanoma.Primary melanocytic tumors of the meninges remain among some of the rarest neoplasms. Again, a variety of entities fall under such a category, including: pigmented meningioma, melanocytic schwannoma, pigmented primitive neural-ectodermal tumor, diffuse melanosis, and meningeal melanocytoma. Of interest, is the entity of purely melanocytic origin that arises from the dura, that being meningeal melanocytomas (MM).
