title: [Nasal neuroendocrine carcinoma].
abstract: OBJECTIVE
  To recognize and understand further nasal neuroendocrine carcinoma (NNC), improve the diagnosis and therapeutic effect.

  RESULTS
  The patients were pathologically confirmed to be neuroendocrine carcinomas. 5 cases were of small cell type, 2 undifferentiated, 1 poorly differentiated. One patient died 14 months after treatment. 2 cases were lost for follow-up. The others were still in treatment.
