Although primary ELTMDs cannot be regarded as anaplastic ependymoma or ependymosarcoma, the recurrent tumor in case 2 predominantly displayed a classic low‐grade ependymoma histology, including perivascular pseudorosettes with an accentuated perivascular staining pattern of GFAP, and dot‐like and ring‐like patterns of cytoplasmic EMA positivity (Figure 4). This evidence concerns the gene GFAP and anaplastic ependymoma.
