Clinical Trial Summary

Inhalation of beryllium can induce specific sensitization and diffuse pulmonary granulomatosis called chronic beryllium disease (CBD). The clinical, radiographic, and anatomopathological features of CBD are very similar to those of sarcoidosis, another granulomatosis, making its diagnosis difficult. In addition, the progression of CBD is poorly understood. The investigators hypothesis is that there are specific clinical, biological, anatomopathological, and radiological presentation specificities of CBD, as well as a worse prognosis compared to pulmonary sarcoidosis.
