Olfactory neuroblastoma or "esthesioneuroblastoma" is an infrequent embryonate tumor, derived from the neuroblasts belonging to the nasal ramification of sensory-olfactory system, which seat is the neuroectodermic respiratory epithelium that was described in 1924 originally. The most common presentation is a polypoid growth that provokes epistaxis or nasal obstruction with a large natural history of anosmia. It is very recurrent locally, thought regional or distant metastases have been reported. This work was aimed at characterizing a male patient from the pathologic view point who attended to the Maxillofacial Surgery Service at "Abel Santamaria Cuadrado" University Hospital, Pinar del Rio, presenting an increase of volume on the hemiface in relation to the left maxillary sinus. This patient was under treatment because of a maxillary sinusitis, the incisional biopsy showed an esthesioneuroblastoma with frontal metastasis. Since this is a rare entity, it is described.
