title: Penicillamine-induced elastosis perforans serpiginosa treated successfully with isotretinoin.
abstract: Elastosis perforans serpiginosa (EPS) and the elastotic changes of pseudoxanthoma elasticum (PXE) are rare but well-recognized side-effects of long-term penicillamine therapy. A 42-year old female patient who developed both of these cutaneous side-effects following treatment with high-dose penicillamine for Wilson's disease is described; near-complete resolution of the EPS, but not the PXE was achieved by treatment with isotretinoin (0.5 mg/kg/day) for 6 weeks, despite continuation of the penicillamine.
