Long term use of D-penicillamine for Wilson's disease can be associated with many adverse reactions and systemic side effects. We report the case of a 28-year-old male patient diagnosed with Wilson's disease presenting with a serpiginous raised violaceous skin lesion in the anterior aspect of the neck over the last six months and two small papules with central umbilication during the last month. Histopathological examination of skin lesions demonstrated transepidermal perforating channel, and the Verhoeff's-van Gieson stain showed marked increase number of irregular serrated elastic fibers suggesting the diagnosis of D- penicillamine induced elastosis perforans serpiginosa.
