Abstract:
Lichen planus pigmentosus (LPP) is an uncommon variant of lichen planus that presents clinically as hyperpigmented, dark brown macules or patches in sun-exposed areas and flexural folds. LPP has been described previously as a pigmented form of actinic lichen planus or as erythema dyschromicum perstans. Recently, however, these diseases have been recognized as different clinical entities. Histopathologically, in atrophic epidermis, vacuolar alteration of the basal cell layer and scarce lymphohistiocytic lichenoid infiltration and pigment incontinence are seen. Herein, we report a case of LPP that developed in a unilateral linear pattern, probably in relation to Blaschko's lines.
