The bullae are formed by an immune reaction, initiated by the formation of IgG [citation needed] autoantibodies targeting dystonin, also called bullous pemphigoid antigen 1, [6] and/or type XVII collagen, also called bullous pemphigoid antigen 2, [7] which is a component of hemidesmosomes. A different form of dystonin is associated with ...
Bullous pemphigoid is primarily a disease of older adults and it rarely occurs in children. The vast majority of cases involved individuals between the ages of 60 and 80 years. Two European studies have also suggested the increased risk of bullous pemphigoid with advancing age. [28] [29]
[6] [7] It is useful in differentiating between the diagnosis of pemphigus vulgaris or mucous membrane pemphigoid (where the sign is present) and bullous pemphigoid (where it is absent). The Nikolsky sign is dislodgement of intact superficial epidermis by a shearing force, indicating a plane of cleavage in the skin epidermal-epidermal junctions ...
Paraneoplastic pemphigus (PNP) is an autoimmune disorder stemming from an underlying tumor.It is hypothesized that antigens associated with the tumor trigger an immune response resulting in blistering of the skin and mucous membranes.
In this variety of pemphigus, the disease process often involves the lungs, causing bronchiolitis obliterans (constrictive bronchiolitis). Though much less frequent, it is still found the most in the Ashkenazi Jewish population. Complete removal of and/or cure of the tumor may improve the skin disease, but lung damage is generally irreversible.
Esophageal webs are associated with bullous diseases (such as epidermolysis bullosa, pemphigus, and bullous pemphigoid), with graft versus host disease involving the esophagus, and with celiac disease. [5] Esophageal webs are more common in white individuals and in women (with a ratio of 2:1).

When the disease is active and widespread, however, the therapy for pemphigus foliaceus is, in general, similar to that for pemphigus vulgaris. In general, immunosuppressive agents, such as azathioprine , mycophenolate mofetil and cyclophosphamide , when combined with corticosteroids, may result in gaining early control of the disease and an ...
