text: Genetic mutations 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, a soft, hemorrhagic, polypoid appearance, and rich, fragile vascular supply are characteristic findings of esthesioneuroblastoma. On microscopic histopathological analysis, arrangements of cells into rosettes or pseudorosettes are characteristic findings of esthesioneuroblastoma.
