[Small cell neuroendocrine carcinoma of larynx: a case report].

Small cell neuroendocrine carcinoma（SCNC） of larynx is very rare. Primary small cell neuroendocrine carcinomas constitute less than 0.5% of all laryngeal cancers. Tumor can occur in any laryngeal subsite, while the supraglottis is the most common. Patients usually complaint with hoarseness and neck mass. The diagnosis of this kind of carcinomas relies strictly on histopathological examination and immunohistochemical testing. The prognosis of laryngeal SCNC is generally poor. Here, we report a case of a 55-year-old-male patient who presented with a poorly differentiated SCNC of the supraglottic larynx and neck mass.
