A case is presented of meningeal melanocytoma that invaded the thoracic spinal cord of a 71-year-old woman. The light and electron microscopic features of the lesion indicate that it derives from melanocytes normally found in the leptomeninges. This tumor closely resembles the dermal cellular blue nevus and does not have the ultrastructure of a meningioma. "Melanotic meningioma" is consequently a misnomer and the name "meningeal melanocytoma" is more appropriate. These tumors may appear to be benign histologically, but they are locally aggressive. Total surgical excision offers the best chance for cure.
本文报告一例71岁女性的脑膜黑素细胞瘤侵犯胸段脊髓的病例。病变的光镜和电镜特征表明，它起源于软脑膜中正常存在的黑素细胞。该肿瘤与皮肤细胞性蓝痣极为相似，不具备脑膜瘤的超微结构。因此，“黑素性脑膜瘤”是一个不恰当的名称，“脑膜黑素细胞瘤”这一名称更为合适。这些肿瘤在组织学上看似良性，但具有局部侵袭性。手术全切是获得治愈的最佳机会。
