====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
