Neuroblastoma

ALK-related neuroblastic tumor susceptibility results from heterozygosity for a germline ALK activating pathogenic variant in the tyrosine kinase domain that predisposes to neuroblastic tumors. The spectrum of neuroblastic tumors includes neuroblastoma, ganglioneuroblastoma, and ganglioneuroma. Neuroblastoma is a more malignant tumor and ganglioneuroma a more benign tumor. Depending on the histologic findings ganglioneuroblastoma can behave in a more aggressive fashion, like neuroblastoma, or in a benign fashion, like ganglioneuroma. At present there are no data regarding the lifetime risk to an individual with a germline ALK pathogenic variant of developing a neuroblastic tumor. Preliminary data from the ten reported families with ALK-related neuroblastic tumor susceptibility suggest that the overall penetrance is around 57% with the risk for neuroblastic tumor development highest in infancy and decreasing by late childhood. [from GeneReviews]

Neuroblastoma

Neuroblastoma is a malignant tumor of neural crest cells, the cells that give rise to the sympathetic nervous system, which is observed in children. [from ORDO]

MedGen UID:
798120
Concept ID:
CN205405
Disease or Syndrome
3.

Neuroblastoma

Neuroblastoma is a solid tumor that originate in neural crest cells of the sympathetic nervous system. Most neuroblastomas originate in the abdomen, and most abdominal neuroblastomas originate in the adrenal gland. Neuroblastomas can also originate in the thorax, usually in the posterior mediastinum. [from HPO]

Neuroblastic tumors

A group of nervous system tumors which display neuronal differentiation. It includes tumors that are composed of immature round cells and tumors that display advanced differentiation and the formation of ganglion cells. [from NCI]

Ependymoblastoma

A rare type of primitive neuroectodermal tumor (PNET) that usually occurs in young children under the age of 2 and is histologically distinguished by the production of ependymoblastic rosettes. It is associated with an aggressive course and a poor prognosis. [from SNOMEDCT_US]

Peripheral neuroepithelioma

The Ewing sarcoma family of tumors (primitive neuroectodermal tumors; PNET) comprise morphologically heterogeneous tumors that are characterized by nonrandom chromosomal translocations involving the EWS gene on chromosome 22q12 and one of several members of the ETS family of transcription factors. The tumors include Ewing sarcoma, peripheral neuroepithelioma, and Askin tumor. In approximately 90% of cases of ESFT, the FLI1 gene (193067) on chromosome 11 is the fusion partner of EWS; in approximately 10%, the EWS fusion partner is the ERG gene (165080) on chromosome 22. Many other ETS family members have been identified as fusion partners of EWS, but these cases are rare (Khoury, 2005). [from OMIM]

Primitive neuroectodermal tumor

An aggressive malignant embryonal neoplasm arising from the central nervous system. This category includes ependymoblastoma, medulloepithelioma, and supratentorial primitive neuroectodermal tumor. It usually follows an aggressive clinical course. [from NCI]

Neuroepithelial neoplasm

Neoplasms composed of neuroepithelial cells, which have the capacity to differentiate into NEURONS, oligodendrocytes, and ASTROCYTES. The majority of craniospinal tumors are of neuroepithelial origin. (From Dev Biol 1998 Aug 1;200(1):1-5) [from MeSH]

Neuroectodermal neoplasm

A neoplasm 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. [from HPO]
