The patient was referred to dermatology. Suspecting pemphigus vulgaris (PV), the physician performed shave biopsies for histopathology and direct immunofluorescence of facial vesicles/bullae to confirm the presumed diagnosis. The patient was started on 60 mg of prednisone daily until the pathology confirmed PV. Steroid-sparing therapy was then discussed and started 2 weeks after initial presentation.
