title: Olfactory Neuroblastoma: A Case Report.
abstract: A 43-year-old female presented with persistent nasal congestion with intermittent epistaxis without resolution for the preceding 5 years. Clinical examination revealed a large pink rubbery mass, medial to the middle turbinate in the right nasal cavity extending to the choana. Radiographic images demonstrated a heterogeneously enhancing lobular soft tissue mass filling the right nasal cavity, causing lateral bowing of the right medial orbital wall and extending posteriorly to the right anterior ethmoid sinus. The clinical, radiographic, histologic, and immunohistochemical features of olfactory neuroblastoma are discussed.
