Dupilumab may be an alternative option in the treatment of acquired reactive perforating collagenosis combined with AD

Abstract

Abstract The management of acquired reactive perforating collagenosis (ARPC) is challenging. Here, we shared two cases of ARPC combined with elderly atopic dermatitis (AD) that did not respond well to conventional treatment but responded well to the monotherapy of dupilumab, which suggests that dupilumab may be an alternative option for the treatment.
