CASE REPORT
A 58-year-old woman presented with a one-month history of hair loss and lesions on her scalp and face. Two years ago, she was diagnosed as systemic lupus erythematosus because of a facial butterfly rash, recurrent oral ulceration, and positive serum tests of ANA and dsDNA. The systemic lupus erythematosus was well controlled by oral prednisone 15 mg/day and hydroxychloroquine 400 mg/day. Hair loss of the scalp with black dots and scaly erythematous plaques and papules were found on the scalp and face (figure 1A and B). Dermoscopy examination of the scalp revealed corkscrew hairs and comma hairs (figure 1A inset).
