ABSTRACT
Background@#Discoid lupus erythematosus (DLE) with alopecia of the scalp can result in permanent hair loss. Therefore, it is important to evaluate skin lesions and establish appropriate treatment plans for scalp DLE with alopecia. @*Objective@#We aimed to investigate the dermoscopic features of scalp DLE with alopecia and to determine the correlation between dermoscopic findings and treatment efficacy. @*Methods@#Thirty-one patients histopathologically diagnosed with scalp DLE and alopecia were included. We reviewed clinical photographs and dermoscopic findings of the patients and evaluated their treatment responses. @*Results@#The most frequent dermoscopic features of DLE with alopecia were follicular keratotic plugs (96.8%), white scales (71.0%), telangiectatic vessels (67.7%), and pigmentation (64.5%); followed by absent follicular openings (48.4%), white structureless areas (35.5%), follicular red dots (16.1%), and perifollicular whitish halo (12.9%). After at least 6 months of treatment, hair regrowth was observed in 22 patients (71.0%). Dermoscopic findings showed that white structureless areas, perifollicular whitish halo, absent follicular openings (especially when the alopecic patch involved >25% of the scalp), and moderate to severe telangiectatic vessels were associated with absence of hair regrowth. @*Conclusion@#Dermoscopy is a promising tool for evaluating lesions and predicting therapeutic outcomes in scalp DLE with alopecia. It may contribute to the establishment of appropriate treatment plan by determining whether hair loss is reversible.
