title: A case of lichen planus pigmentosus that was recalcitrant to topical treatment responding to pigment laser treatment.
abstract: Lichen planus pigmentosus is a rare variant of lichen planus for which no effective treatment is currently available. Patients usually present with hyperpigmented, dark brown macules on sun-exposed areas or flexural folds. Here we describe a 50-year-old Chinese woman who had biopsy-confirmed lichen planus pigmentosus that was recalcitrant to a variety of topical treatments, but responded to treatment with a pigment laser.
