Neuroendocrine Tumors

Tumors whose cells possess secretory granules and originate from the neuroectoderm, i.e., the cells of the ectoblast or epiblast that program the neuroendocrine system. Common properties across most neuroendocrine tumors include ectopic hormone production (often via APUD CELLS), the presence of tumor-associated antigens, and isozyme composition. [from MeSH]

Metaiodobenzylguanidine

A guanidine analog with specific affinity for tissues of the sympathetic nervous system and related tumors. The radiolabeled forms are used as antineoplastic agents and radioactive imaging agents. (Merck Index, 12th ed) MIBG serves as a neuron-blocking agent which has a strong affinity for, and retention in, the adrenal medulla and also inhibits ADP-ribosyltransferase. [from MeSH]

14.

A lesion characterized by the presence of neoplastic neuroepithelial cells with palisading nuclei. This lesion implies a morphologic growth pattern and it is not considered a clinicopathological entity. [from NCI]

MedGen UID:
154309
Concept ID:
C0555199
15.

An aggressive malignant embryonal neoplasm arising from the central nervous system. It is characterized by the presence of multilayered rosettes formation, and increased cellularity. Symptoms include increased intracranial pressure, hydrocephalus, and focal neurological signs. [from NCI]

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]

Guanidine

A strong organic base existing primarily as guanidium ions at physiological pH. It is found in the urine as a normal product of protein metabolism. It is also used in laboratory research as a protein denaturant. (From Martindale, the Extra Pharmacopoeia, 30th ed and Merck Index, 12th ed) It is also used in the treatment of myasthenia and as a fluorescent probe in HPLC. [from MeSH]

Astroblastoma

A rare glial neoplasm more commonly found in young adults. It is characterized by tumor cells with characteristics suggestive of an astrocytic origin (positive for GFAP), arranged perivascularly. The cells have broad, non-tapering processes radiating towards a central blood vessel. The biologic behavior of astroblastomas is variable, so no WHO grade has been established, yet. (Adapted from WHO.) [from NCI]

Medulloepithelioma

A rare, unilateral, benign or malignant embryonic neoplasm typically presenting as a cilliary body mass during childhood. It is composed of medullary epithelial cells. [from NCI]
