Abstract
Elastosis perforans serpiginosa (EPS) is now a well-recognized potential complication of long-term penicillamine therapy. By itself, EPS appears to be a relatively innocuous cutaneous side effect of penicillamine. However, suspicion has been raised in recent literature that EPS may represent only a superficial manifestation of more serious penicillamine-induced systemic elastic tissue damage, particularly involving blood vessels. This is a report of a patient with Wilson's disease who was treated with penicillamine for 14 years. She developed EPS, and histologic examination of the skin revealed the characteristic penicillamine-induced “lumpy-bumpy” elastic fibers in the dermis. More important, nonlesional skin showed the same elastic fiber changes. Of greatest significance was the finding of identical elastic fiber alterations in an artery.
