A mediastinal squamous cell carcinoma and thyroid carcinoma were found in an aged horse. Clinical signs consisted of bilateral thyroid gland enlargement, chronic cough, and mild respiratory distress. The neoplasms were not treated. Squamous cell carcinoma is a common neoplasm in horses, but not in the cranial portion of the mediastinum. Thyroid carcinomas in horses are uncommon. This combination of neoplasms is rare and may have been associated with a defect in the immune system.
在一匹老龄马中发现了纵隔鳞状细胞癌和甲状腺癌。临床症状包括双侧甲状腺肿大、慢性咳嗽和轻度呼吸窘迫。这些肿瘤未接受治疗。鳞状细胞癌是马常见的肿瘤，但在纵隔的头端部分并不常见。马的甲状腺癌并不常见。这种肿瘤组合很罕见，可能与免疫系统缺陷有关。
