Head Neck 2016, 38 Suppl 1:E2259–66. Tumor behavior varies within the spectrum of sinonasal tumors with neuroendocrine differentiation, and a broad distinction should be made between tumors of neuroectodermal origin, e.g., olfactory neuroblastoma [ONB]) and those of epithelial origin (e.g., sinonasal neuroendocrine carcinoma (SNEC).
