gliofibroma
An astrocytic tumor affecting young people. Morphologically, it is characterized by the presence of collagenous tissue surrounding neoplastic astrocytes. In some cases the collagen is produced by the tumor cells (desmoplastic astrocytoma), whereas in others it is produced by mesenchymal cells (mixed glioma/fibroma).
