title: Dural mesenchymal chondrosarcoma. Case report.
abstract: A dural mesenchymal chondrosarcoma is reported in a 19-year-old man. This tumor had features of angioblastic meningioma (meningeal hemangiopericytoma), by light microscopy. However, ultrastructurally this tumor could be distinguished from angioblastic meningioma, and its similarity to extracranial mesenchymal chondrosarcoma was confirmed.
