TROAP and glioblastoma: Findings represented weak/negative staining for TROAP in normal brain sample, moderate to strong cytoplasmic staining for TROAP in low‐grade glioma (such as Pilocytic astrocytoma, Pleomorphic xanthoastrocytoma and Oligodendroglioma) and high‐grade glioma (such as Anaplastic Oligodendroglioma and Glioblastoma Multiforme) tissues (Figure 2A,B).
