Abstract:
A 57-year-old female suffering from plaque psoriasis for 25 years developed acquired reactive perforating collagenosis and then bullous pemphigoid three months later. Although there have been several reports of bullous pemphigoid in patients with psoriasis, the coexistence of all three autoimmune skin diseases in a patient has not been described. The aim of this article is to present the clinical case of the 57-year-old female with these three autoimmune skin diseases and to emphasise the need for a treatment plan that takes into account the different immunopathogenesis of each condition, so that treating one disease will not result in exacerbation of the others.
