Meanwhile, some pathological markers are of great significance in differentiating schwannoma from other tumors: EMA for differentiating from epithelial-derived tumors, NF for differentiating from neuron-derived tumors, GFAP and Olig2 for differentiating from glial cell-derived tumors, and D2-40 for differentiating from lymphoma. Here, OLIG2 is linked to schwannoma.
