Pemphigus vulgaris associated with rheumatoid arthritis in a patient not taking penicillamine

D-penicillamine is one of the disease-modifying anti-rheumatic drugs (DMARDs). Drug-induced pemphigus is not frequently associated with D-penicillamine, and to date, the number of reported cases is about a hundred. Most reports of D-penicillamine-induced pemphigus vulgaris are in patients with rheumatoid arthritis. It has rarely been reported in patients not taking D-penicillamine. We report a case of pemphigus vulgaris in a 48-year-old female patient with rheumatoid arthritis, not taking penicillamine.
