The clinical presentation, aetiology, diagnosis, and management of this condition are discussed. The patient developed ... Esthesioneuroblastoma (ENB) is an uncommon malignant neoplasm of the nasal vault, believed to arise from the olfactory epithelium. The tumour was first described in 1924 by Berger and colleagues, and given the name esthésioneuroépithéliome olfactif.1 Uncertainty about the precise histological origin has led to the use of various names

Immunohistochemistry profile (figure 2c and 2d) showed positivity for neural marker namely neuron specific enolase.The tumor cells were negative for epithelial markers cytokeratin and epithelial membrane antigen (figure 2e and 2f) Hence a diagnosis of adult esthesioneuroblastoma of nasal cavity was made.

Pathological features of low-grade and high-grade esthesioneuroblastoma (ENB) (A–C) Low-grade ENB: (A and B) this tumor shows a typical lobular architecture and is composed of nests of small round cells. No mitosis or nuclear atypia is observed. 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.

Controversy still exists regarding the role of pathologic grading (Hyams grade) in prognostication. Staging esthesioneuroblastoma Esthesioneuroblastoma is a rare cancer that starts in the nervous system cells responsible for smell. The most common staging system for esthesioneuroblastoma is the Kadish staging system.
