Mediastinal squamous cell carcinoma and thyroid carcinoma in an aged horse.
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.
