-*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.
