The Role of Dermoscopy in Severity Assessment of Alopecia Areata: A Tertiary Care Center Study

OBJECTIVE: To evaluate the dermoscopic features of alopecia areata (AA) and correlate these features with patterns and severity. DESIGN AND SETTING: The present study was performed over a period of six months, from September 2018 to February 2019, in a tertiary care hospital where clinically diagnosed patients with AA were enrolled. A thorough clinical examination followed by dermoscopy was performed. The results were tabulated and then analyzed statistically. PARTICIPANTS: The study included 52 patients with AA of either sex and all age groups. Patients whose diagnosis was unclear and those who received treatment for their AA in the month prior to the study were excluded. RESULTS: The mean age of presentation was 22.8±12.1 years. The most common dermoscopic finding was presence of black dots (BD) seen in 82.7 percent of patients; the least common was tulip hairs (TH), seen in 9.6 percent. Significant associations between yellow dots (YD) and broken hair (BH) and severity of alopecia was observed. There was a significant correlation of alopecia areata disease pattern with YD and BH (p<0.05). CONCLUSION: This study highlights the potential use of dermoscopy in AA as a means to understand various disease characteristics that can act as predictors of severe disease or poor prognosis.
