Neuroectodermal Tumors Malignant neoplasms arising in the neuroectoderm, the portion of the ectoderm of the early embryo that gives rise to the central and peripheral nervous systems, including some glial cells.
Synonyms : Neuroectodermal Tumor, Tumor, Neuroectodermal, Tumors, Neuroectodermal
Neuroectodermal Tumors, Primitive A group of malignant tumors of the nervous system that feature primitive cells with elements of neuronal and/or glial differentiation. Use of this term is limited by some authors to central nervous system tumors and others include neoplasms of similar origin which arise extracranially (i.e., NEUROECTODERMAL TUMORS, PRIMITIVE, PERIPHERAL). This term is also occasionally used as a synonym for MEDULLOBLASTOMA. In general, these tumors arise in the first decade of life and tend to be highly malignant. (From DeVita et al., Cancer: Principles and Practice of Oncology, 5th ed, p2059)
Synonyms : Cerebral Primitive Neuroectodermal Tumor, Neoplasms, Primitive Neuroepithelial, Neuroectodermal Tumor, Primitive, Neuroepithelial Neoplasms, Primitive, Primitive Neuroepithelial Neoplasms, Ependymoblastomas, Medulloepitheliomas, PNETs, Spongioblastomas
Neuroectodermal Tumors, Primitive, Peripheral A group of highly cellular primitive round cell neoplasms which occur extracranially in soft tissue and bone and are derived from embryonal neural crest cells. These tumors occur primarily in children and adolescents and share a number of characteristics with Ewing's Sarcoma (SARCOMA, EWING'S). They may arise from the chest wall, skin, orbit, kidney, and other structures and tend to be locally invasive or metastasize, although relatively benign forms may occur. Characteristic histologic features include a tendency to form Homer-Wright rosettes and to stain positively with neuron-specific enolase and vimentin. (From DeVita et al., Cancer: Principles and Practice of Oncology, 5th ed, p2113; J Clin Oncol 1998 Mar;16(3):1150-7)
