title: Penicillamine dermatopathy with lymphangiectases. A clinical, immunohistologic, and ultrastructural study.
abstract: The term penicillamine dermatopathy refers to the characteristic hemorrhagic skin lesions found in persons receiving long-term penicillamine therapy for either Wilson's disease or cystinuria. These lesions are thought to develop as a result of faulty collagen and elastin synthesis. We describe a patient with Wilson's disease who developed extensive penicillamine dermatopathy. In addition, histologic, immunochemical, and ultrastructural studies revealed multiple lymphangiectases with blood vessel to lymphatic anastomosis within these lesions, a finding not previously reported. The possible relationship to defective collagen and elastin formation are considered.
