  Fig. 1. Metastatic tumor in the lymph node. (A) In the lower-left corner is a normal lymph node structure; in the remaining areais the metastasis. (B, C) Higher magnification view of the metastasiscystic and papillary structures (B) with a single-row cuboidal-columnar epithelium in the myxoid and vascularized stroma (arrows) (C). Lumens contain mucinous material.

• 

  Fig. 2. Histopathological findings suggest that the tumor is originated from the central nervous system, consistent with myxopapillary ependymoma metastasis. (A) Periodic acid-Shiff–Alcian blue histochemical stain shows the presence of acidic mucin. (B) Epidermal growth factor receptor positivity of the tumor cells by immunohistochemistry (IHC). (C) Glial fibrillary acidic protein positivity of the tumor cells by IHC. (D) Vimentin positivity of the tumor cells by IHC.
