Clinicopathological Characteristics and Recurrence Patterns of Olfactory Neuroblastoma: A 15-Year Tertiary Center Case Series

Objectives

Olfactory neuroblastoma (ONB) is a rare malignant tumor of the sinonasal tract with heterogeneous clinical behavior and recurrence potential. Due to its low incidence, prognostic factors and optimal treatment strategies remain incompletely defined. The objective of this study was to describe the clinicopathological characteristics, treatment approaches, and recurrence patterns of ONB over a 15-year period at a tertiary referral center.
