Dermatology showed scattered dark brown macules on the backs of both hands and both lower extremities, the edges raised on the normal skin, and the fingernails of the right hand were thinned, central longitudinally raised, and longitudinally split. Combined with clinical and typical pathological, the diagnosis of lichen planus pemphigoid was made. After one month of treatment, the skin lesions of the patients were significantly improved and the itching was relieved.
