Pemphigus is a group of autoimmune bullous diseases that is mainly classified into pemphigus vulgaris (PV) and pemphigus foliaceus.1 PV is further subcategorized into a mucocutaneous type (with autoantibodies against desmoglein (Dsg) 3 and Dsg1) and a mucosal type (with autoantibodies against Dsg3 but not Dsg1) based on autoantibody profile and clinical features. Pemphigus vegetans (PVeg), a rare variant of PV, is characterized by vegetating lesions. However, the mechanism behind the occurrence of these elevated lesions remains unclear.2 Recently, it was reported that anti-desmocollin (Dsc) 1 and Dsc3 autoantibodies were frequently detected and potentially pathogenic in PVeg.3 Here we report a case of PV in which a vegetative plaque occurred during treatment accompanied by the elevation of anti-Dsc1 autoantibodies.
