Abstract: Some literature has reported that alopecia areata is a complication of drug hypersensitivity reaction syndrome. We report a case of a patient with drug-induced hypersensitivity syndrome who developed the complication of alopecia areata six months after the appearance of the rash, and gradually progressed to alopecia universalis two months later. After 2 weeks of treatment with baritinib, the rash was reduced, but no obvious hair growth was observed.

Key words: drug-induced hypersensitivity syndrome, alopecia areata, alopecia universalis, autoimmune diseases
