Background: Neuroendocrine neoplasms (NENs) of the nasal cavity, paranasal sinuses and nasopharynx account for a wide spectrum of histotypes. They can range from indolent form to highly aggressive tumors. Olfactory neuroblastoma, like most sino-nasal NENs, represents a rare neoplasm that prompts diagnostic pitfalls. From a morphological perspective, olfactory neuroblastoma can mimic many nasal neoplasms but a proper recognition is mandatory for its aggressive behaviour.
Case presentation: A case of olfactory neuroblastoma in a 85 years old woman is reported. The neoplasm has been surgical removed from the nasal cavity with a clinical and radiographic diagnosis of nasal polyp. Correct diagnostic definition has needed a complete histological and immunohistochemical characterization of the tumoral tissue in surgical pathology laboratory.
Conclusion: The correct diagnosis of olfactory neuroblastoma directs the clinical management that is unique for this neoplasm in comparison to other nasal ones. Bicranial-facial surgery or a trephination procedure represent the most common approach for the treatment of this malignancy. Their success determine disease prognosis.
