NCI Definition: 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. [1]

Olfactory neuroblastomas most frequently harbor alterations in SUFU, IKZF1, CTCF, CDKN2C, and YES1 [2].

Most Commonly Altered Genes in Olfactory Neuroblastoma

CDKN2C Loss, YES1 Amplification, TRIM37 M556V, TP53 R306*, and TP53 Nonsense are the most common alterations in olfactory neuroblastoma [2].
