====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
