Recently, it has been reported that a small number of AD patients experience immune drift after receiving dupilumab treatment, leading to a transition from eczema-like lesions to psoriasis-like lesions. Here, we report a case of pustular psoriasis caused by dupilumab treatment for atopic dermatitis. This case underscores the diagnostic challenges associated with immune drift related to biological agents while also highlighting the shortened time frame for immune drift onset compared to previous reports.Keywords: immune drift, dupilumab, atopic dermatitis, pustular psoriasis
