Immunohistochemical staining revealed that the tumor was positive for reticular fiber staining, BRAFV600E, Syn, Olig-2, and CD34 and scattered positive for glial fibrillary acidic protein (GFAP) and neuron-specific nuclear protein (NeuN), and Ki-67 was low (approximately 2%–5%). Here, GFAP is linked to neoplasm.
