Pemphigus vulgaris (PV) is an autoimmune disorder resulting from the interaction between autoantibodies and desmoglein. Here, we report a case of PV developed after 5-aminolaevulinic acid-based photodynamic therapy (ALA-PDT). The harmful and deleterious effects of UV radiation on the onset, during course, and perpetuation of PV have been observed for decades. Correlation between reactive oxygen species (ROS) and PV have also been reported. Oxidative proteins, which are modified by ROS, and subsequent production of antibodies by immune system seem to be responsible for PV developed following ALA-PDT. We emphasize that ALA-PDT should be added to the list of possible factors triggering PV and this condition should be considered if blistering arises following ALA-PDT.
