Equine Oral, Esophageal and Rectal disorders

Oral masses

Neoplasia

Squamous cell carcinoma is  the most common oral tumor.  Local bone destruction is often advanced before obvious clinical signs
develop. SCC is frequently associated with bone destruction and extension to lymph nodes. Excision and/or radiation therapy may be possible in some cases.

Dental tumors  are usually benign and slow growing. Most respond to local excision.

It is possible to remove the entire rostral lower jaw (from the incisors to the interdental space) for ossifying fibromas and other tumors. This is a referral procedure. Horses can eat normally but tend to have the tongue exposed.
