A peripheral primitive neuroectodermal tumor arising from the middle turbinate and transnasal endoscopic approach for its surgical treatment

SummaryMalignant peripheral primitive neuroectodermal tumors (pPNETs) account for very little in all sarcomas. Sinonasal involvement is encountered even very rarely. In this case report, a very uncommon growth of pPNET in a 10-year-old girl arising from the lateral side of the middle turbinate in the sinonasal region was described and its treatment by transnasal endoscopic approach and chemotherapy was discussed.
