gingival hyperplasia/hypertrophy
fibrous epulis of the peridontal ligament

excluding the above the majority of oral tumors in dogs are malignaceies

90% are malignant

pigmented and non pigmented

microscopically composed of malanocytes

can occur on the tongue, tonsil, gingiva

usually locally invasive but can metastasize to regional LN

20% of oral neoplasms

locally invasive

see proliferation of mesenchymal cells with variable amounts of collagen

Front 26

What are oral papillomas?

Back 26
