Neuroepitheliom des N. olfactorius

Olfactory neuroepithelioma (9523/3) is a rare tumor which mimics olfactory neuroblastomas (9500/3) in presentation and imaging features and is often used synonymously with the latter .

Pathology

Olfactory neuroepitheliomas differ from olfactory neuroblastomas in a number of ways :

• neural processes and glandular differentiation
• rarely secrete catecholamines
• express cytokeratin
• express Ber-EP4
