Abstract:
Drug-induced pemphigus (DIP) is a special type of pemphigus, and its pathogenesis, characteristics of treatment, and prognosis are closely related to the inducing drugs. This article reports the diagnosis and treatment of DIP (pemphigus vulgaris) caused by the administration of rifampin to a patient with tuberculosis. Combined with the literature, we discussed the types, pathogenesis, differential diagnosis, and treatment principles of DIP. We propose that in the oral clinical practice for patients with pemphigus vulgaris, the importance of investigating suspected drugs that induce DIP should be emphasized.
