A neuroectodermal neoplasm is a neoplasm or tumor of the neuroectoderm.1 They are most commonly tumors in the central or peripheral nervous system.

Tumors exhibiting neuroectodermal differentiation are classified into two main groups:2

  • Group I tumors/neoplasms: neuroendocrine carcinomas. These show predominantly epithelial differentiation. They include pituitary adenoma and carcinoid tumor
  • Group II tumors/neoplasms: nonepithelial neuroectodermal neoplasms. These are predominantly neural in origin. They include melanoma, olfactory neuroblastoma, and Ewing's sarcoma.
