The discovery of one case of silicosis in a ceramic plant-an industry considered a low silicotic risk - led to an X-ray examination of all the workers, which found a high number of cases among them. Radiological findings are described; the majority of which were small, regular opacities in the lungs. It is important to remember that this one case led to the discovery of many more in ceramic plants all over the state.
