Abstract

Lichen planus pigmentosus-inversus (LPP-inversus) is an extremely rare variant of lichen planus (LP), and only a few cases have been reported. Its course is characterized by exacerbations and remissions, and it is known to be more chronic than classical LP is. We report two cases of LPP-inversus and offer the suggestion that LPP-inversus may originate from LP of flexural areas.

Keywords: Lichen planus pigmentosus-inversus; Lichen planus-inversus.
