| |
| − | *The common benign epithelial tumour of the [[Oral Cavity - Oropharynx - Anatomy & Physiology|oropharynx]] is the papilloma, which is very often caused by infection with certain types of species-specific papilloma viruses.

| |
| − | *Squamous cell carcinomas are the malignant equivalent of the papilloma and may arise anywhere within the [[Oral Cavity - Oropharynx - Anatomy & Physiology|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 - Pathology|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 [[Oral Cavity - Oropharynx - Anatomy & Physiology|oropharynx]] in cattle are commonly seen as part of an [[Oesophagus - Pathology#Upper Alimentary Tract Carcinoma Complex|upper alimentary tract carcinoma complex]].
