Overview
Esthesioneuroblastoma, also known as olfactory neuroblastoma, is a rare form of cancer involving nasal cavity and believed to arise from the olfactory epithelium. It can cause loss of vision, and taste.[1] Esthesioneuroblastomas are undifferentiated tumors of neuroectodermal origin derived from the olfactory epithelium. The tumor cells are mitotically active and are the precursor cells that develop into sustentacular and neuronal cells. They usually present as a soft tissue mass in the superior olfactory recess involving the anterior and middle ethmoid air-cells on one side and extending through the cribriform plate into the anterior cranial fossa.[2]
Historical Perspective
Esthesioneuroblastoma was first discovered by Berger and Luc, in 1924.[3]
Classification
Based on the duration of symptoms, esthesioneuroblastoma may be classified into two subtypes neuroblastoma proper and neuroendocrine carcinomas.[4]
Pathophysiology
Genes involved in the pathogenesis of esthesioneuroblastoma include chromosomal gains in 7q11 and 20q and deletions in 2q, 5q, 6p, 6q, and 18q. On gross pathology, soft and hemorrhagic, polypoid appearance, and rich and fragile vascular supply of the tumor are characteristic findings of esthesioneuroblastoma. On microscopic histopathological analysis, arrangements of cells into rosettes or pseudorosettes are characteristic findings of esthesioneuroblastoma.[5][6][7][8][9][10][11]
Causes
Differential Diagnosis
Esthesioneuroblastoma must be differentiated from other tumors with similar histological appearance, such as lymphoma, Ewing sarcoma, melanoma, olfactory/ other [rhabdomyosarcoma or Merkel cell carcinoma], neuroblastoma, and small cell carcinoma. Distinguishing esthesioneuroblastomas from the other tumors is of paramount importance because the tumors respond differently to various treatment modalities.[5][12]

Esthesioneuroblastoma is a rare form of cancer involving nasal cavity and believed to arise from the olfactory epithelium. The tissue of origin is not yet well characterized.
