Melanomas
Papillomas
- The common benign epithelial tumour of the oropharynx is the papilloma, which is very often caused by infection with certain types of species-specific papilloma viruses.
Squamous cell Carcinoma
- Squamous cell carcinomas are the malignant equivalent of the papilloma and may arise anywhere within the oropharynx.
- Those arising over the tonsil (squamous carcinoma of the tonsil or tonsillar carcinoma) are very malignant, invading adjacent tissues and metastasising early.
- Squamous carcinomas of the tongue (especially in cats) can also behave in a very malignant fashion. Those at more rostral sites, e.g. on the incisor gingivae, are less likely to metastasise early although they may be locally aggressive.
- Squamous cell carcinomas of the oropharynx in cattle are commonly seen as part of an upper alimentary tract carcinoma complex.
Other Neoplasms
- Both benign and malignant connective tissue tumours do occur,
- e.g. fibroma, fibrosarcoma, osteoma, osteosarcoma.

Stick injuries in dog
- Sticks may damage to pharynx with oedema and swelling in pharynx and secondary infection.
- Pieces of wood may remain embedded in back of throat resulting in chronic inflammation.
- Can kill dog.
