A Clinicopathological Study of Sinonasal Neuroendocrine Carcinoma and Sinonasal Undifferentiated Carcinoma

Abstract

SNUC and SNEC are both aggressive tumors, usually presenting in middle age as a nasal mass. Both tumors have the capacity to metastasize locally and distantly, and both can result in poor outcomes. This small series precludes a demographic or prognostic distinction between the two groups.
