In EWSR1-PLAGL1 fusion cases the absence of OLIG2 and SOX10 staining with relatively solid growth pattern are ependymal-like features, though ependymoma type EMA staining was only convincingly present in one case [Fig. 2B] with focal/rare paranuclear dot-like staining in two cases. This evidence concerns the gene EWSR1 and ependymoma.
