P32 - Alimentary Flashcards
palatoschisis
- cleft palate
- failure of fusion of lateral palatine process
- caused by genetic mutation
cheiloschisis
- cleft lip “hare lip”
- may interfere with suckling
partial thickness loss of epithelium
- erosion
full thickness necrosis of epithelium
- ulcer
clinical signs of stomatitis and gingivitis
- ptyalism (hypersalvation)
- oral pain
- inappetence
- dysphagia (trouble swallowing)
what systemic illness can lead to oral lesions (2)
- kidney disease (uremic syndrome)
- feline immunodeficiency virus (FIV)
1st and most consistent sign of feline immunodeficiency virus (FIV)
- gingivitis
lesions of FIV associated with
- reduction of CD4 lymphocytes
4 diseases that can cause vesicular stomatitides
- foot and mouth disease
- vesicular stomatitis
- vesicular exanthema of swine
- swine vesicular disease
parapoxvirus disease of oral cavity (2)
- bovine popular stomatitis
- contagious ecthyma (orf)
histopathology of parapoxvirus disease
- proliferation and necrosis with eosinophilic cytoplasmic inclusion bodies
necrotizing disease of oral cavity (2)
- calf diphtheria
- noma
calf diphtheria clinical signs (4)
- swollen cheeks
- inappetence
- pyrexia
- halitosis
noma lesions typically begin as
- necrotizing gingivitis that extends into adjacent bone causing severe tissue destruction and sometimes death
most likely pathogenesis of eosinophilic stomatitis and gingivitis (feline eosinophilic granuloma disease)
- hypersensitivity of other immune-mediated mechanism suspected
feline lymphoplasmacytic stomatitis and gingivitis characterized by
- chronic inflammation and painful mouth with reddened and ulcerated gingival mucosa
most likely pathogenesis of feline lymphoplasmacytic stomatitis and gingivitis
- inefficient mucosa immunity and overgrowth or oral bacteria suspected
canine chronic ulcerative paradental stomatitis (CUPS) pathogenesis
- dental plaques contain bacteria that release inflammatory mediators and toxins
pemphigus vulgaris lesions
- vesicular to pustular lesions -> then rupture leaving ulcers
pathogenesis of pemphigus vulgaris
- acanthyolysis of epithelium
- caused by autoantibodies to desmosomal proteins in stratified squamous epithelium
gingival hyperplasia most common in
- dogs (brachycephalic breeds)
- 30% in boxers older than 5
canine benign oral neoplasia (2)
- benign papiloma
- oral plasmacytoma
canine malignant neoplasia (3)
- malignant melanoma
- squamous cell carcinoma
- fibrosarcoma
what percentage of oral canine melanocytic tumors are malignant
- 90%
amelanotic melanoma
- oral melanoma that is non-pigmented and range from white to pinkish tan
what malignant oral neoplasia frequently affects tonsils and tongue in dog
- squamous cell carcinoma
feline malignant neoplasia (2)
- squamous cell carcinoma
- fibrosarcoma
squamous cell carcinoma is what percentage of all oral neoplasms in cats
- 60%
what malignant oral neoplasia frequently affects ventrolateral tongue and tonsils of cats
- squamous cell carcinoma
