By IHC, tumor cells showed only focal, weak staining or were negative for Olig2, BCL-6 interacting corepressor protein (BCOR), nuclear protein in testis family member 1 protein (NUTM1), neuronal nuclei protein (Neu-N), neurofilament, glial fibrillary acid protein (GFAP), p53, SALL4, epithelial membrane antigen (EMA), and lin-28 homolog A (Lin28A). Here, LIN28A is linked to neoplasm.
