Pemphigus/pemphigoid antibodies were determined, obtaining the positive result of anti-desmoglein 1 (anti-DSG1) antibodies 1:40 (consistent with pemphigus erythematosus), anti-desmoglein 3 (anti-DSG3) antibodies 1:20 (BIOCHIP, Euroimmun, Germany), and antibodies on monkey esophagus substrate 1:20 (IIF, Euroimmun, Germany) (Table 1, Figure 2). This evidence concerns the gene DSG3 and pemphigus erythematosus.
