It is often difficult to determine whether SNUC is a distinct pathologic entity with poorly differentiated neuroendocrine features or it represents an undifferentiated tumor of squamous lineage. Also, reliable histopathologic markers that distinguish SNUC from poorly differentiated sinonasal squamous cell carcinoma (SNSCC) are lacking. Therefore, identification of new diagnostic molecular markers for SNUC is needed.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Treatment\u2010na\u00efve tumor specimens obtained from 15 SNUC and 6 SNSCC patients were used.
