Currently, reports on BLP are rare. Our department admitted one patient in March 2024. After laboratory examination and skin pathological examination, it was diagnosed as bullous lichen planus and treated with a combination of traditional Chinese and Western medicine. After the combination of traditional Chinese and Western medicine treatment, the rash on the whole body gradually flattened, the color became darker, the blisters disappeared, the itching symptoms were relieved, the swelling on the tongue and lips disappeared, and the eroded surface healed. The anti-BP180 antibody turned negative after re-examination, and there was a significant therapeutic effect. The medical history data is now integrated and discussed as follows.
