- Whole of back of mouth covered in ulcerative granulation tissue.
- Chronic, tends to start at angle of jaw (bilateral), progression quite slow but over weeks affects whole of back of mouth.
- May also affect anatomy and physiology of the tongue.
Pathology
Epithelium lost over whole of mucosa, lots of macrophages, lymphocytes and proliferating fibrous response at base.
Pathogenesis
- Probably viral.
- Calicivirus found in 7-80%, also often find picorna virus and Feline Immunodeficiency Virus
- Probably calici virus that starts it.
- Also owners often claim develops after 'having cold' prior to it.
- Calici virus infection may be followed by autoimmune / exaggerated immune response which produces lesions.
- Will heal eventually, but takes time and cat loses lots of condition.
