Abstract:
A 34-year-old man presente wiith progressive anosmia, epistaxis, and
intracranial hypertension related to a nasal tumor with intracranial
extension. After surgical resection of the lesion, inmunohistochemical and
electrical microscopy study of the biopsy material stablished the
diagnosis of esthesioneuroblastoma or olfactory neuroblastoma. This is a
rare embrionary tumor derived from neuroblasts of the olfactory sensorial
system. That portion of the olfactory tract is located at the upper half
of the nostrils, above the cribiform plate. Esthesioneuroblastoma shows a
bimodal incidence with a first peak in the second decade, and a second and
most important peak during the third and fifth decades of live.
Individuals from both sexes are similarly affected. Pollipoid mass with
epistaxis or nasal obstruction and chronic anosmia are the most common
clinical manifestations of this tumor. It is invasive and frequently
causes regional and distant metastasis; however, some tumors could stay
without recognition until its intracranial growing through the cribiform
plate causes neurologic symptoms.
