The desmoglein (Dsg) enzyme-linked immunosorbent assay (ELISA) is a sensitive and specific test for pemphigus vulgaris (PV),1,2 which, during pregnancy, is exceedingly rare.3 To our knowledge, the clinical patterns of PV activity monitored using Dsg ELISA during pregnancy and after delivery have not been reported. Transplacental anti-Dsg antibody transfer has not previously been confirmed using Dsg ELISA.
