abstract: Chronic beryllium disease is an occupationally acquired granulomatous lung disease similar to sarcoidosis. It is caused by exposure to beryllium in genetically susceptible persons. It should be suspected in patients with beryllium exposure who present with pulmonary symptoms or have a positive screening blood beryllium-specific lymphocyte proliferation test. The diagnosis is confirmed by the finding of granulomas on transbronchial biopsy in the appropriate clinical and epidemiologic setting. Although there is no cure, treatment with corticosteroids is usually beneficial. In view of the potential side effects, treatment is reserved for patients with symptoms or a decline in pulmonary function.
