[Olfactory esthesioneuroma manifesting as Schwartz-Bartter syndrome].
BACKGROUND
Olfactory esthesioneuroblastoma is an uncommon neuroectodermal tumor originating from the olfactory epithelium, which is rarely associated with hormone excess syndrome.


METHODS
Asymptomatic olfactory esthesioneuroblastoma was diagnosed in a 22-year-old man who presented a syndrome of inappropriate antidiuretic hormone secretion. Following surgery, the immunohistochemical analysis demonstrated the existence of neurophysin hormone in tumoral cells.


CONCLUSIONS
This case provides evidence that olfactory esthesioneuroblastoma can be uncovered by inappropriate antidiuretic hormone secretion.
