title: Mixed pneumoconiosis: silicosis, asbestosis, talcosis, and berylliosis.
abstract: Mixed pneumoconiosis is pulmonary disease due to two or more inhaled mineral irritants. Chronic disease due to beryllium has not been a component of any described mixed pneumoconiosis. A man with occupational exposure to a combination of dusts developed severe pulmonary disease. Silicosis, talcosis, asbestosis, and berylliosis were all documented by an open biopsy of the lung. The varieties of mixed pneumoconiosis are summarized.
