A case of carcinoid of the larynx was reported and other 8 cases collected from the literature were analysed. The average age of the patients was 66.8 years, which was 5-10 years older than that of patients with squamous carcinoma of the larynx. Carcinoid is rarely present in the larynx. The route of the spread is mainly through the blood stream rather than local infiltration. The prognosis for patients with carcinoid of the larynx is more favorable than that of squamous carcinoma of the larynx, but more serious than that of carcinoid of the lung and intestine. The 5-year survival rate was less than 50%. Histochemical study revealed that the carcinoid of the larynx was one of the foregut type, and might arise from neuroendocrine cells of the ectoderm.
报告了1例喉类癌病例，并对从文献中收集的其他8例病例进行了分析。患者的平均年龄为66.8岁，比喉鳞状细胞癌患者的年龄大5至10岁。类癌在喉部很少见。其扩散途径主要是通过血流而非局部浸润。喉类癌患者的预后比喉鳞状细胞癌更有利，但比肺和肠道类癌更严重。5年生存率低于50%。组织化学研究表明，喉类癌是前肠型之一，可能起源于外胚层的神经内分泌细胞。
