Medical records were reviewed for 11 horses with squamous cell carcinoma of the larynx and/or pharynx. The average age at presentation was 15.3 years. No breed or sex predilection was present. At presentation, 6 of 11 horses were dyspneic and 4 horses had inspiratory stridor. Endoscopy was performed in all cases and was more useful in demonstrating a mass in the laryngopharyngeal region than laryngeal or guttural pouch radiography. Surgical excision was attempted in 3 horses and in 1 horse alleviated clinical signs for 4 months. Ten horses were euthanatized and 1 horse died. Results of this study indicated that laryngopharyngeal squamous cell carcinomas are difficult to surgically excise due to their location, size and invasiveness. Treatment is often not attempted because of the advanced state of the disease at the time of presentation.
对11例患有喉和/或咽鳞状细胞癌的马匹病历进行了回顾。就诊时的平均年龄为15.3岁。不存在品种或性别偏好。就诊时，11匹马中有6匹呼吸困难，4匹马有吸气性喘鸣。所有病例均进行了内镜检查，与喉部或咽囊造影相比，内镜检查在显示喉咽区域肿块方面更有用。对3匹马尝试进行手术切除，其中1匹马的临床症状缓解了4个月。10匹马实施了安乐死，1匹马死亡。本研究结果表明，喉咽鳞状细胞癌因其位置、大小和侵袭性而难以手术切除。由于就诊时疾病已处于晚期，通常不尝试进行治疗。
