Abstract
A 35-year-old female presented with 13-year history of unilateral recurrent nasal mass, epistaxis and facial pain. Nasal examination revealed a pale glistening mass in the right nasal cavity. On probing, mass was insensitive to touch and bled on handling. Computed tomographic scan showed a mass filling the right nasal cavity, ipsilateral maxillary and ethmoid sinuses. Diagnosis of pansinusitis polyposis was made.Transnasal endoscopy-assisted excision of the mass was done, and the diagnosis of olfactory neuroblastoma was established by histopathology and confirmed by immunohistochemistry. The mass was classified as a Kadish stage B tumor. Further intervention including medial maxillectomyand ethmoidectomy, and complete endoscopic-resection of the tumor from cribriform plate was done via lateral rhinotomy approach. The tumor was found adhered to the lateral wall-the middle meatus and was easily peeled away from the cribriform plate and ethmoids. Patient was referred for radiotherapy. No evidence of loco-regional recurrence or systemic metastasis observed at 10-month follow-up.
