Systemic sclerosis (scleroderma) in two iron ore mines
Faculty of Medicine, Memorial University of Newfoundland St. John's, Newfoundland, Canada, A1B 3V6
Six males with systemic sclerosis were observed in the work forces of two iron ore mines. The usual spectrum of clinical features encountered in systemic sclerosis patients were present. Histologic examination of pulmonary tissue was performed on three of the cases and showed features of both silicosis and scleroderma but to different degrees and stages of development. Exposure to high levels of silica-containing dusts had occurred in all six cases.
