silicon and Scleroderma--Systemic

We describe four women who presented with systemic sclerosis several years after cosmetic augmentation mammoplasty with silicone-gel implants. The interval between implantation mammoplasty and the onset of systemic sclerosis ranged from 6 to 15 years. All patients fulfilled the criteria established by the American Rheumatism Association for systemic sclerosis and had Raynaud phenomenon, arthralgia, and evidence of pulmonary or gastrointestinal involvement. Enlargement of lymph nodes draining the prostheses was noted in two patients. Antinuclear antibodies were detected in three patients and showed speckled or nucleolar patterns. Removal of the prostheses in two cases did not result in improvement of systemic sclerosis. Evidence of silicone leakage from the implants included the following. The observation by light microscopy of refractile particles in tissues distant from the prostheses, the observation by electron microscopy of electron-dense structures consistent with silica, and the definitive identification of the element silicon by energy-dispersive analysis in these electron-dense structures. A marked, chronic inflammatory infiltrate containing lymphocytes, "foamy" histiocytes, and larger numbers of multi-nucleated giant cells with vacuoles and asteroid bodies was found at the same sites. Our demonstration that silicone escapes from elastomer-silicone-gel breast implants and appears to be closely associated with a chronic inflammatory reaction suggests that silicone plays a role in the development of certain cases of systemic sclerosis.

A 68-year-old white woman was referred to us by her rheumatologist for possible participation in a clinical study of photopheresis for scleroderma. In February 1993, she noticed edema of her distal phalanges, Raynaud's phenomenon in both hands, flu-like symptoms, fatigue, intermittent diarrhea, abdominal pain, tearing in both eyes, dyspnea on exertion, dysphagia, and odynophagia. Bilateral silicone-gel breast implants had been placed 12 years before; 2 months before her present evaluation, they were removed and found to be ruptured. Physical examination revealed edema, limited to the fingers and hands bilaterally, and slight induration of the skin on the dorsum of both hands and distal forearms. The remainder of the physical examination was normal. According to our study protocol, a skin biopsy specimen from the dorsum of the right hand was taken, but all other laboratory investigations were refused. Histopathologic examination revealed multiple clear spaces of varying sizes in the dermis and multinucleated macrophages containing small refractile particles, characteristic of silicone granuloma (Figs. 1 and 2); however, the specimen showed no evidence of scleroderma. X-ray energy dispersive analysis by scanning electron-microscopy confirmed the presence of elemental silicon in the small refractile particles. The patient did not receive any treatment after her diagnosis and shortly thereafter, she was lost to follow-up.
