Abstract


Neuroendocrine tumors (NETs) of the sinonasal tract are rare in occurrence. According to the 2017 World Health Organization classification of the primary head and neck neuroendocrine carcinomas, they can be classified as follows: well-differentiated, moderately differentiated, and poorly differentiated types. Among these, welldifferentiated and moderately differentiated neuroendocrine carcinomas of the sinonasal tract are extremely rare.
Based on a recent proposal, well-differentiated and moderately differentiated neuroendocrine carcinomas are also called neuroendocrine tumor grade 1 and 2, respectively. Because of its rarity and the lack of studies, treatment guidelines for NETs of the sinonasal tract have not been established yet. We report a case of NET grade 2 of the nasal cavity in a 46-year-old man treated by endoscopic sinus surgery. To the best of our knowledge, this is the first case report on an NET grade 2 of the nasal cavity in South Korea.
