ABSTRACT

Lichen planus pigmentosus (LPP) is uncommon variant of Lichen planus (LP). Lichen planus is a common inflammatory condition of unknown etiology. Here we report a60-year-old female presented with 7 months history of persistent very itchy skin lesions on her hands. Otherwise, she is healthy. Skin examination revealed non-scaly brownish patches on her palms. Hair, nail and mucous membranes examinations were all normal. Skin biopsy showed hyperkeratosis, hypergranulosis, acanthosis, saw toothing of rete ridges, vacuolar degeneration of the basal layer and band-like lymphohistiocytic cellular infiltrates in the papillary dermis. The patient was diagnosed as LPP. She was started on potent topical steroid treatment with excellent response.
