Mandibular squamous cell carcinoma in a young horse.

摘要

Squamous cell carcinoma (SCC) is a frequently reported neoplasm in the horse. However, oral forms are uncommon and represent only 7% of all SCC. A literature review reveals a total of 13 cases of oral SCC with no apparent sex or breed predisposition but predominantly adult and old horses, mean age 16.5 years. This case report describes a 3.5-year-old pony filly that was presented for investigation of a mandibular fistula of 3 weeks' duration. The clinical and histopathological findings of mandibular squamous cell carcinoma in this filly are described in detail.
