“…Moreover, keratin plugs were observed only in patients with DLE in this study. Keratin plugs are believed to be associated with pilosebaceous atrophy through the inflammatory process9. Yellow dots are reported as a specific finding of AA1; however, they were also observed in patients with TM and TA in this study.…”

BackgroundVarious kinds of alopecia can show small round or oval hairless patch. Dermoscopy could be a simple, useful tool for making a correct diagnosis.ObjectiveThe aim of this study is to investigate clinical usefulness of dermoscopy for diseases with small round or oval hairless patch on the scalp.MethodsDermoscopic examination was performed for 148 patients with small round or oval hairless patch using DermLite® II pro. The type and its patient number of alopecia investigated in the study were as below: alopecia areata (n=81), trichotillomania (n=24), tinea captis (n=13), traction alopecia (n=12), lichen planopilaris (n=8), discoid lupus erythematosus (n=7), congenital triangular alopecia (n=2) and pseudopelade of Brocq (n=1). The significance of dermoscopic findings for each disease were evaluated.ResultsCharacteristic dermoscopic findings of alopecia areata were tapering hairs and yellow dots. Those of trichotillomania and traction alopecia were broken hairs. Dermoscopic findings of tinea capitis included bent hairs, perifollicular white macules and greasy scales. Discoid lupus erythematosus and lichen planopilaris were characterized by dermoscopic findings of lack of follicular ostia. Furthermore, keratin plugs were frequently seen in discoid lupus erythematosus whereas perifollicular hyperkeratosis and erythema were frequently seen in lichen planopilaris.ConclusionDermoscopic examination for small round or oval hairless patch showed characteristic findings for each disease. Based on these results, we propose dermoscopic algorithm for small round or oval hairless patch on the scalp.

“…The finding of BM thickening is specific and suggests chronic interface injury, therefore atypical of BS. 28 Although rarely reported to occur in dermatomyositis 29 and lichen sclerosus et atrophicus, 30 BM thickening is a relatively specific finding for LE.…”
