Squamous cell carcinomas are the '''malignant''' equivalent of the papilloma and may arise anywhere within the [[Oropharynx - Anatomy & Physiology|oropharynx]]. These tumours are formed from '''epidermal cells''' with varying degrees of '''squamous cell differentiation'''. They are common in the cat, dog, horse and cow but can occur in other species. They are most likely to develop in '''non-pigmented areas''' of the skin as there is a known association between their development and exposure to '''UV light'''.
