Vesicles, bullae (blisters) and pustules |
Vesicles, bullae and pustules are superficial
lesions with a liquid content.
The two first ones can only secondarily become pustulent by
overlaying infections. The
pustule initially contains pus and is very rare in th oral mucosa.
These lesions are rarely found intact when occuring inside the
mouth, since masticatory trauma ruptures them rather easily.
Vesicles are primarily formed by spongiosis of an eczema or by a
ballooning and reticular degeneration during viral infections.
The mechanism by which a blister is formed is fundamental to confirm the
diagnosis of the underlying disease. Blisters may be intraepithelial, by
acantholysis of the spiny cells, as occurs in the different types of
pemphigus, or subepidermal separating the connective tissue from the
epithelium as occurs in the pemphigoidal lesions: Duhring’s disease,
erythema multiforme, and bullous pemphigoid.
