Category:Oral Cavity - Vesicular Pathology

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:

1. Ingestion of hot food (corrosive liquids)
2. 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.
