Lichen planus pigmentosus
Abstract
Lichen planus pigmentosus (LPP) is an uncommon variant of lichen planus of unclear etiology that predominantly affects patients of skin types III to VI. We report a case of LPP of two years duration in a 67-year-old man involving upper extremities, chest, abdomen, and upper back.
