Introduction: Esthesioneuroblastoma (EBN) is a rare and malignant tumor of olfactory epithelium. Due to its infrequency, there are several controversies regarding its treatment, being the endoscopic approach a new option. Objective: describe a young male case of EBN, its challenging diagnosis and options of treatment. Case report: 21 year old man who presented with a two month history of difficulty breathing and hyposmia after undergoing nasal vein cauterization for recurrent epistaxis. Physical examination confirmed a mucosal mass obstructing his left nostril. Magnetic Resonance Imaging of the face demonstrated a mass within the nasal septum infiltrating the oropharynx, hard palate, cribriform plaque and orbital lamina of the ethmoid bone. Endovascular embolization was performed followed by transsphenoidal endoscopic surgical excision. Anatomopathological and immunohistochemistry analysis confirmed the diagnosis of EBN. Repeat MRI-face showed a residual lesion requiring open craniotomy in addition to radio-chemotherapy. Conclusion: EBN is an uncommon malignant tumour arising in the superior aspect of nasal cavity. There is no consensus regarding optimal treatment strategies. Endoscopic transsphenoidal resection is reserved to early stages only and its use on advanced disease has been poorly explored.
