Oral Cavity - Vesicular Pathology

Content

▼ Oral Cavity - Vesicular Pathology
Foot and Mouth Disease
Oral Vesicles in Dogs
Swine Vesicular Disease
Vesicular Stomatitis Virus

Pathology

Damage to prickle cells (stratum spinosum).
Appears as accumulation of fluid within epithelium, quickly erodes leaving hyperaemic stratum germinativum.
Heals by proliferation of new cells, so long as infection does not continue.

Pathogenesis

May be caused by:

Ingestion of hot food (corrosive liquids)
Systemic viral diseases. e.g:
1. Foot and Mouth disease - ruminants and pigs
2. Vesicular Stomatitis Virus - horse, pigs, cattle
3. Vesicular Exanthema - pigs

N.B. All are indistinguishable from FMD clinically.

-====Pathology====
-=====Gross=====
-#Initially - hyperaemia of mucosa (e.g. catarrhal inflammation) then within 12 hours produces fluid filled vesicles on dorsum of [[Oral Cavity - Tongue - Anatomy & Physiology|tongue]], may be other places
-#Small vesicle coalesce to produce big ones -i.e. Bullae
-#Very quickly rupture; epithelium appears dirty grey in colour because of necrosis - sloughed skin, very good for diagnosis
-#Leave painful, hyperaemic epithelium
-#Looks like "ulcer "with ragged edge but not a true ulcer as stratum germinativum retained and will rapidly heal completely in about 2 weeks unless becomes secondarily infected
-=====Microscopic lesions=====
-*Degeneration of prickle cells
-*Cells "balloon" as fill with fluid and then die to produce vesicle containing straw coloured or clear fluid
 ===[[Swine Vesicular Disease]]===
-*May produce vesicles in mouth that are indistinguishable from foot and mouth disease
-*Swine vesicular disease produces sporadic large outbreaks
-**Approximately 5% have lesions in mouth, foot lesions much more common
-===Vesicles in dogs===
+===[[Oral Vesicles in Dogs]]===
-*Vesicles in mouth are often caused by hot food - especially in dogs.
-*Can produce quite big vesicles, but will heal.
-*No major problems associated with vesicles on [[Oral Cavity - Tongue - Anatomy & Physiology|tongue]] in dogs (except if due to drinking battery acid, but this also produces vomiting).
