ABSTRACT
Although primary neuroendocrine carcinomas(NEC) are uncommon tumors of the larynx, they represent the most common nonepidermoid malignancy of this organ. Whereas typical carcinoid tumors and small-cell carcinomas occur very rarely in the larynx, the majority of laryngeal NEC belong to a broad intermediate group between these two extremes of NEC. Through many case studies, a major protion of clinicopathologic characteristics of laryngeal NEC have been revealed; however, the gistogenesis of laryngeal NEC is still unknown. The only well-documented normal neuroendocrine structures of the larynx are paraganglions, but the incidence of laryngeal paragangliomas are much lower than that of NEC. Here, we report on three cases of NEC affecting the larynx and the results of searching for neuroendocriene cells in non-neoplastic larynx tissue.
