Abstract
A 63‐year‐old woman had d‐penicillamine‐induced pemphigus with a high index value of circulating autoantibodies against desmoglein 1. Because of the lack of response to prednisolone monotherapy, the patient was treated with a combination therapy of mizoribine and low‐dose prednisolone. The skin eruption was improved by this combination with a declined value of circulating anti‐desmoglein 1 antibody. Currently, a remission of 2 months has been achieved, and prednisolone could be tapered.
