A neuroectodermal neoplasm is a neoplasm or tumor of the neuroectoderm.[1] They are most commonly tumors in the central or peripheral nervous system.[citation needed]
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 malignant melanoma, olfactory neuroblastoma and Ewing's sarcoma.
