The aim of the study was to evaluate the role of the neural factor in the pathogenesis of nonsegmental vitiligo (NSV) by...

Pigmentary demarcation lines over the face.

BACKGROUND We have been observing that a significant proportion of our patients, especially females, have certain pigmentary demarcation lines (PDL) over the face. However, systematic studies of the subject are lacking. AIMS We categorized the different clinical patterns of facial PDLs in the Indian subpopulation and assessed their prevalence in this study. METHODS About 4000 consecutive pa...
