“…Lack of follicular ostia is indicative of scarring alopecia5. In addition, in this study, the lack of follicular ostia was frequently observed in cases of scarring alopecia such as DLE, LPP, and PB.…”

“…However, some of these approaches are invasive and not always available. Dermoscopy was recently introduced as a useful technique for diagnosing various hair and scalp diseases, including AA, TM, androgenic alopecia, TC, DLE, LPP, or inherited hair shaft dystrophies1,2,3,4,5,6. The reports did not emphasize the dermoscopic differences among various forms of alopecia, but focused only on describing the dermoscopic findings of each disease.…”

Dermoscopic Approach to a Small Round to Oval Hairless Patch on the Scalp

et al. 2014

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.

“…These are an expression of melanophages in papillary dermis and indicate incontinentia pigmenti. They are a feature of two scalp diseases, namely LED and LPP, where they assume two different aspects: in LPP, blue-gray dots appear with a ‘target pattern' due to the circular arrangement of melanin around the perifollicular area, sparing the interfollicular area [16], unlike LED, where blue-gray dots follow a speckled pattern indicating an involvement of the interfollicular areas with a sprinkling of melanin in these areas [7,17]. …”

Clinical, Histological and Trichoscopic Correlations in Scalp Disorders

et al. 2015

View full text Add to dashboard Cite

Trichoscopy is the term coined for the dermoscopic imaging of scalp and hair. This diagnostic technique, simple and noninvasive, can be used as a handy bedside tool for the diagnosis and follow-up of hair and scalp disorders. It allows the recognition of morphologic structures not visible by the naked eye and provides the clinician with a range of dermoscopic findings necessary for differential diagnosis. Trichoscopy observation can be broadly grouped as interfollicular patterns and follicular patterns. Recently, a third mixed class, called the follicular plus interfollicular pattern, has been introduced. Some of these features are specific to a certain scalp disease, while others can be found in many hair disorders. Although studies suggest that the use of trichoscopy can improve clinical accuracy, further investigation is needed. This review provides update information on the trichoscopic features of the most common scalp disorders, striving to show a histopathological and clinical correlation.
