title: [Granulomatous lung lesions after occupational exposure to glass fibers].
abstract: 39 years old man with granulomatous lesions in both lungs caused by occupational contact with glass fibers was described. He has been working as an bricklayer-plasterer for 18 years and was in contact with lime, cement, plaster, asbestos, dust of coal and wood and with glass fibers. For the last two years before admission in 1993 he has had frequent bronchial infections. On admission he was in good general condition, his spirometric examination and blood gases were within normal limits. On chest x-ray disseminated lesions were found. Those lesions were of the round shapes on chest CT. Many sputum cultures for tubercle bacilli were negative. ANA and ANCA were not found in the serum. ACE was within normal limits. No precipitins to environmental antigens were found. Cancer metastases were suspected and lung biopsy during videothoracoscopy was done. Many foreign body type granulomas were found throughout the specimen. The character of the lesions was not typical for tuberculosis, sarcoidosis, extrinsic allergic alveolitis, silicosis or asbestosis. There are some reports concerning the possibility of development of such lesions after the exposition to glass fibers. We suspect that case is an example of such pathology. His occupational exposition was stopped in 1993 and he was observed without treatment. During the 5 years of observation (up till 1998) he was in good health with stable chest x-ray picture and results of respiratory system function.
