Abstract:
Lichen planus pigmentosus (LPP) is a rare variant of lichen planus, and it is characterized by hyperpigmented, dark brown to violaceous colored macules or patches on the sun exposed areas of the skin. The term of LPP-inversus was proposed to describe some cases with LPP arising on the intertriginous areas. Clinically, LPP-inversus is characterized by well defined dark brown to violaceous macules or patches with minimal symptoms and it is predominantly confined on the flexural areas. The histological characteristics are a lichenoid inflammatory infiltrate on the upper dermis, melanophages and pigmentary incontinence. The clinical course can vary. We present here an additional case of LPP-inversus that developed on the both inguinal folds and we review the relevant literature.
