Definitions related to olfactory neuroblastoma:
-
A rare neuroectodermal tumor originating from olfactory receptor cells in the nasal cavity or paranasal sinuses. Microscopically, it is characterized by neuroblastic differentiation with occasional formation of rosettes. If the tumor is not resected at an early stage, the prognosis is usually poor.NCI ThesaurusU.S. National Cancer Institute, 2021
-
(esthesioneuroblastoma, olfactory) A malignant olfactory neuroblastoma arising from the olfactory epithelium of the superior nasal cavity and cribriform plate. It is uncommon (3% of nasal tumors) and rarely is associated with the production of excess hormones (e.g., SIADH, Cushing Syndrome). It has a high propensity for multiple local recurrences and bony metastases.

(paranasal sinus olfactory neuroblastoma) An olfactory neuroblastoma arising in the paranasal sinus.NCI ThesaurusU.S. National Cancer Institute, 2021

Esthesioneuroblastoma (ENB), also known as olfactory neuroblastoma, is a rare neoplasm originating from olfactory neuroepithelium. Approximately 1,000 cases have been identified since Berger and Luc described the first case in 1924.WebMD, 2019

Esthesioneuroblastoma (es-thee-zee-o-noo-row-blas-TOE-muh) is a rare type of cancer that begins in the upper portion of the nasal cavity.Mayo Foundation for Medical Education and Research
-
Olfactory neuroblastoma is a rare cancer of the upper part of the nasal cavity called the cribiform plate, which is a bone deep in the skull between the eyes, and above the ethmoid sinuses. It accounts for about 5% of all cancers of the nasal cavity and paranasal sinuses. It develops in nerve tissue associated with the sense of smell...National Center for Advancing Translational Sciences
