With the growing use of biologic agents, there have been remarkable clinical advancements in the treatment of these diseases. Interestingly, during biologic therapy for either condition, a phenomenon has emerged where treatment can paradoxically induce a transition to the phenotype of the other condition.We present two cases of immune drift phenomena caused by biologic agents for treating psoriasis and atopic dermatitis.The first one is a case of psoriasis lesion that developed in an old patient with AD who was treated with dupilumab for two months. The second one is a case of eczematoid lesion that developed in an adult patient with ankylosing spondylitis who was treated with Secukinumab for 1 year.Keywords: immune drift phenomena, secukinumab, dupilumab, psoriasis and atopic dermatitis
