A 17-year-old male presenting with multiple hyperpigmented macules over right side of chest in zosteriform pattern

Lichen planus pigmentosus (LPP) is a variant of lichen planus. It is characterized by small black, brown macules, on sun exposed areas like face, neck, upper extremities and trunk. Lesions are insidious in onset with gradually progressive course. Few variants have been reported like LPP inversus, localized LPP, linear LPP, zosteriform LPP and LPP of oral mucosa etc. Here, we present a case of zosteriform LPP in a young adolescent male, which is a rare presentation.
