Abstract
Primitive neuroectodermal tumors are rare malignancies arising from embryonic neural crest cells. They share characteristics with extraosseous Ewing sarcoma. They usually occur in children and young adults and the most common location is the thoracopulmonary region, abdomen and extremities. These tumors have significant aggressiveness, which determines their poor prognosis. The location in nasal fossa- paranasal cavities is anecdotal. Until now only one previous case has been reported in the located in the nasal fossa.
