title: Dermoscopic findings of alopecia areata in dark skinned individuals: an analysis of 116 cases.
abstract: BACKGROUND
  Several dermoscopic findings in alopecia areata (AA) are characteristic and aid in the diagnosis of this disease. Studies evaluating the clinical significance of these findings in AA in dark-skinned individuals are sparse. There is no literature of correlation of dermoscopic findings to severity of disease.
  
  
  OBJECTIVE
  The aim was to determine the dermoscopic findings of AA in dark skinned individuals and to assess whether certain dermoscopic findings correlate with disease activity and severity.
  
  
  METHODS
  Totally 116 patients with AA were included in the study. After a thorough clinical history and examination to note type, severity and activity of the disease, dermoscopy was performed using a Heine Delta 20 dermoscope (Heine optotechnik,Herrsching, Germany) and the results were noted in a proforma. Statistical analysis was performed using SPSS13 software using appropriate statistical tools.
  
  
  RESULTS
  Dermoscopic findings were nearly similar to that described in western literature. Yellow dots (YDs) were found to be highly sensitive for diagnosis, increased frequency being seen in Indian prepubertal patients when compared with western literature. YDs/field of vision (FOV) were found more frequently in severe types of AA. There was no correlation of dermoscopic findings to severity of disease.
  
  
  CONCLUSIONS
  Dermoscopic features are similar to that described in the literature. However, YDs are seen in higher frequency. YDs/FOV could serve as dermoscopic criteria to grade severity of AA.
