  Fig. 1. (A) Computed tomography scan revealing a well-demarcated mass in intragluteal fold area without connection to the sacrum. (B) Gross picture of extraspinal sacrococcygeal myxopapillary ependymoma. The mass shows a lobular growth pattern and fibrotic texture.

  Fig. 2. (A) Microscopic examination shows a tumor composed of papillary structure with myxohyaline material. (B) Relatively monomorphic cuboidal cells are arranged around the myxopapillary structure (hematoxylin and eosin stain, ×100 [A] and ×400 [B]). (C) The tumor cells are positive for GFAP (left) and S100 protein (right). (D) Ki-67 immunohistochemical stain shows less than 1% nuclear positivity (immunohistochemical stain, ×100 [C] and x40 [D]).
