title: [Nasal primitive neuroectodermal tumor: a case report].
abstract: Primitive neuroectodermal tumor (PNET) is a small round cell malignancies, normally confined to the chest wall and soft tissues of children and young adults, and reports of this tumor existing in nasal cavity are scarce. We herein present a case of nasal PNET. A 35-year-old male patient presented with a chief complaint of stuffy nose was diagnosed with a primary nasal pPNET by the clinical, microscopic, immunohistochemical features. Since these tumors are highly aggressive and patient prognosis is typically very poor, early diagnosis, immediate surgical resection and re-resection if possible, early radiotherapy and chemotherapy and close follow-up are required. We also review literatures on pPNET.
