Dermoscopy in selected disorders of scarring alopecia

Md. Zeeshan, RKP Chaudhary, PK Roy, Abhijeet Kumar Jha


Objective To study the dermoscopic features of  lichen planopilaris (LPP), discoid lupus erythematosus (DLE) and pseudopelade of brocq (PB) affecting the scalp.


Methods Retrospective observational analysis of dermoscopic characteristics of 18 cases with LPP, DLE, PB were studied. Polarised dermatoscope at 10X magnification in polarized mode was used and photographs were captured. The evaluated parameters included perifollicular changes, vascularity, white dots, keratin plugs, number of follicular ostia.


Results Perifollicular scales, white dots and blue-grey dots along with accentuation of honey comb pattern were seen in LPP. Keratin plugs, white dots and blue-grey dots along with branching vessels were seen in DLE. In PB lack of follicular ostia were present.


Conclusion Dermoscopy thus is helpful in differentiating LPP, DLE and PB and obviating the need of biopsy in all cases.
