Psoriasis is a chronic inflammatory condition that is polygenic and multisystemic, impacting approximately 2-3% of the global population. The onset of this disease is influenced by an intricate interplay of genetic and environmental factors, predisposing individuals to the psoriasis phenotype. The complex pathogenesis of psoriasis contains certain key aspects found in other autoinflammatory and autoimmune dermatological diseases.

Bullous pemphigoid (BP) is a debilitating autoimmune skin blistering disease, characterized by the deposition of specific autoantibodies at the dermal-epidermal junction. This leads to an inflammatory cascade involving the activation of complement proteins, mast cell degranulation, immune cell recruitment, and the release of proteases by granulocytes. While several cytokines and signaling pathways have been implicated in the pathogenesis of BP, the precise mechanism behind autoantibody production remains unclear.

Pemphigus is a group of autoimmune bullous diseases mediated by autoantibodies most often of the immunoglobulin G class, subclasses immunoglobulin G1, and immunoglobulin G4 (IgG4), directed against desmosomal adhesion proteins of keratinocytes. This study aimed to evaluate IgG4 immunoreactivity on paraffin sections using immunohistochemistry in patients with pemphigus as a diagnostic test. Fifty formalin-fixed paraffin-embedded specimens from patients with pemphigus were selected.
