Pemphigus vulgaris (PV) is an autoimmune, intraepithelial, blistering disease affecting the skin and mucous membranes. It is mediated by circulating autoantibodies against keratinocyte cell surfaces. Exposure to certain medications like penicillamine and captopril can trigger PV. Such a trigger can happen through the effects on binding to molecules involved in cell adhesion, influence on enzymes that mediate keratinocyte aggregation, and molecules involved in cell and by stimulating neoantigen formation. In addition, NSAID’s, penicillin, cephalosporins have been associated with drug-induced PV.

IgA pemphigus does not present with oral mucosa blisters. Direct and indirect immunofluorescence can both help to differentiate PV from IgA pemphigus.

Pemphigus foliaceus does not affect the oral mucosa and is less common than PV.

Paraneoplastic pemphigus presents with mucocutaneous vesicles and bullae and can be differentiated from PV using indirect immunofluorescence and immunoblot.
