title: Lichen planus pigmentosus.
abstract: Lichen planus pigmentosus, a variant of lichen planus, is a disorder with conflicting taxonomy. Its worldwide recognition is still not fully understood because of insufficient contemporary evidence of the disease in the literature. The authors review the historical background, etiopathogenesis, clinical connotation, atypical variants, and histopathology to highlight its diversity.
