**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.
