~~====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
