Abstract

This case report describes a rare occurrence of coexisting Pigmentary Demarcation Line (PDL) type B and congenital vitiligo in a 4-year-old girl. The patient presented with linear band of hyperpigmentation along the blaschko line on the inner sides of bilateral thighs and lower abdomen, accompanied by depigmented patches on the knees, since birth. The clinical history, examination findings, and histopathological analysis supported the diagnosis. The case sheds light on a potential association between PDL and congenital vitiligo, which is not well-documented in the existing literature. Further research and long-term follow-up are recommended to investigate the underlying mechanisms and potential genetic predisposition, providing a deeper understanding of association between these conditions.
