25
Dental Calculus
Tartar, mineralized plaque
26
Actinomycosis
Lumpy jaw
27
Actinobacillosis
Wooden tongue in ruminants, chronic stomatitis and glossitis
28
Actinobacillus lignieresii
Gram negative rod, creates pyogranulomatous soft tissue lesions, bacteria surrounded by eosinophils on H and E, Splendore-Hoepelli
29
Splendore-Hoeppli Phenomenon
Deposition of immune complexes
30
Thrush
Candidiasis, opportunistic fungal hyphae and yeasts affect mucous membranes in immune suppressed individuals, pseudomembranes on stratified squamous
31
Lingual Lesions
Manifestations of systemic disease
32
Uremic Glossitis
Ulcers on tongue margins due to renal failure
33
Viral Glossitis
BVD and foot and mouth disease in calves and steer
34
Lymphoplasmacytic Gingivitis, Stomatitis
Chronic periodontal disease leads to immune mediated response to bacteria in lesions
35
Feline Chronic Gingivo-Stomatitis
Unclear etiology, similar to lymphoplasmacytic gingivitis, FIV may be involved
36
Chronic Ulcerative Paradental Stomatitis
Periodontal ulcers common in older dogs
37
Canine Vesicular Stomatitides
Rule out immune mediated disease
38
Cat Vesicular Stomatitides
Calcivirus infection
39
Large Animal Vesicular Stomatitides
Rule out viral disease
40
Viral Vesicular Stomatitides
viral induced epithelial damage leads to ballooning degeneration in keratinocytes, forming bullae that can rupture and lead to ulcer
41
Foot and Mouth Disease Virus
Exotic and highly contagious, lesions in oral mucosa and epidermis, vesicles rupture and become ulcers, drooling and lameness, ruminants and pigs
42
Tiger Heart
Stripes of inflammation and necrosis in younger animals infected with foot and mouth disease, acute death without typical lesions
43
Epidermal FMD
Coronary bands of hooves and interdigital spaces
44
Rhabdovirus Vesicular Stomatitis
Ruminants, pig, and horses
45
Swine Vesicular Disease
Enterovirus only in pigs
46
Vesicular Exanthema
Calcivirus in pigs, destruction of keratinocytes and fluid accumulation forming vesicles that ulcerate on snout
47
Bovine Viral Diarrhea
Erosive-ulcerative stomatitides
48
Malignant Catarrhal Fever
Severe and prominent erosive ulcerative stomatitides, always fatal with lymphocytic necrotizing vasculitis
49
Bovine Papular Stomatitis
Parapoxvirus, papules on snout and oral cavity, ulceration demarcated by rings of proliferative mucosa
50
Contagious Ecthyma
Orf, contagious viral pustular dermatitis, proliferative sores around mouth in goat and sheep
51
Oral Necrobacillosis
Necrotizing stomatitis from Fusobacterium necrophorum in cattle, sheep, and swine
52
Calf Diphtheria
Oral necrobacillosis in calves, ulvcerative necrotizing inflammation of buccal, pharyngeal, and laryngeal mucosa
53
Feline Eosinophilic Granuloma Complex
Nodular or ulcerative
54
Gingival Hyperplasia
Nodular, teeth can become buried in lesions, common in older brachycephalic dogs, boxers
55
Epulis
Fibromatous or ossifying benign tumor of periodontal ligament and dental mesenchyme
56
Acanthomatous ameloblastoma
Locally aggressive and recurring tumors, previously classified as epulis
57
Canine Oral Papillomatosis
Papillomavirus induce lesions in lips and oral mucosa, transient and regresses with age
58
Histology of Canine Papillomatosis
Verrucous, thick keratinized stratified squamous epithelium over pedunculate connective tissue core
59
Oral Melanoma
Common in dogs and mostly malignant, small breed and oral pigmentation predispose
60
Amelanotic Melanoma
Oral melanomas can be unpigmented
61
Melanoma Metastasis
Rapid metastasis to lungs, some lesions may be amelanotic clones
62
Squamous Cell Carcinoma
Common on tongue in dog and cat
