[Olfactory esthesioneuroma. Apropos of 12 cases]

Abstract

The authors report a 12-case series of olfactory esthesioneuromas, in which they review the main characteristics of this rare tumor. The olfactory esthesioneuroma diagnosis should be evoked for all nasal tumors, especially for tumors originating in a high position. This diagnosis is confirmed by the difficult pathological examination, which currently benefits widely from immunohistochimy. Prognosis is poor and surgery is the main treatment, associated with varying degrees of radiotherapy. As far as chemotherapy is concerned, its role must be clarified.
